I've been there: the search for the perfect roommates can feel like an impossible mission. But the secret isn't finding the perfect person; it's avoiding the dumbest mistakes that turn an apartment into a battlefield.
Why choosing a roommate is more important than that new couch
Think about it for a second. You can have the most beautiful home in the world, but if you share it with someone who drives you crazy every time you walk into the kitchen, that home becomes a prison. The person you share your space with affects your mood, your sleep, and even your performance at school or work.
That's why investing time in the selection process is the smartest thing you can do. And to do it right, you first need to know what NOT to do. Here are the 5 cardinal sins I see people commit all the time.
Mistake #1: Choosing the friend, not the roommate
Like I said, this is the all-time classic. You think, "Awesome! I'll move in with Mark, we have so much fun together!" Too bad Saturday night fun has nothing to do with running a household.
Being social is one thing; daily compatibility is another. You might discover your friend is a loud night owl while you're up at 6 AM, or that their idea of "clean" is drastically different from yours. I'll be honest with you: sometimes it's easier to get along with a near-stranger who has similar habits than with your best friend.
The pro-tip: Before you decide, have an honest chat. Don't talk about parties; talk about real life. What time do you wake up? Do you wash dishes immediately or let them "soak"? Are you a tidy person or a chaos artist? A little transparency upfront saves friendships (and living situations).
Mistake #2: "We'll figure it out later": the silent killer
This is the mistake of anyone who hates conflict. You move in thinking, "Oh well, we'll sort out cleaning and expenses as we go, we're adults." Wrong. The things left unsaid turn into resentment.
Setting clear rules from day one isn't for control freaks; it's for smart people who want a harmonious living situation. Prevention is much, much better than dealing with a massive fight over a finished roll of toilet paper.
The Mystery of the Cleaning Schedule
The number one cause of roommate problems is always the same: filth. Who cleans what? And when? Don't leave it to chance.
Here's the trick: make a cleaning schedule, even a simple one on an Excel sheet or a WhatsApp group. A "house rulebook" with weekly turns for the bathroom, kitchen, and floors. It might sound like a military operation, but it ensures you'll never have to argue about who was supposed to clean the bathroom two weeks ago.
The Black Hole of Shared Expenses
"I still owe you 5 bucks for that detergent from three weeks ago." Sound familiar? Small shared expenses, if not managed, create a toxic atmosphere of debts and credits.
Today, in 2026, there are dozens of apps for splitting expenses. Use them. Create a shared cash fund with $20 from each of you every month to buy detergent, salt, oil, and toilet paper. Total transparency, zero arguments.
The 2 AM Ghost Party
Everyone has a right to a social life, of course. But the home is a shared space. If you know your roommate has an exam or an important meeting the next morning, maybe throwing a party on a Tuesday isn't the idea of the century.
The golden rule is simple: always give a heads-up. "Hey, a couple of friends are coming over for a drink tonight, is that cool with you?" Nine times out of ten, the answer will be "no problem," but that gesture of respect changes everything.
Mistake #3: Ignoring the red flags (and being passive-aggressive)
During your first meetings, people tend to show their best side. But your gut doesn't lie. If you notice something that feels off during the chat, don't ignore it.
Maybe they say, "Oh, I'm super chill, except for when I throw my techno parties in the living room." There you go, that's a red flag the size of a house. Or, if they answer the question "How do you handle cleaning?" with a vague "Oh, you know, when it needs to be done," their idea of "when it needs to be done" is probably very different from yours.
And once you're living together, please, avoid passive-aggressive behavior. Sticky notes left on the fridge ("Someone finished the milk... again!") have never solved anything. They just create a climate of suspicion and tension.
If something is bothering you, take your roommate aside and talk to them. Calmly, without accusing. "Hey, I've noticed the sink has been full a lot lately, can we figure out a better way to manage it together?" It's an approach that opens a dialogue, not a confrontation.
Mistake #4: Thinking your room is an embassy
Yes, your room is your private, sacred space. No one should enter without knocking, and that's non-negotiable. But the home doesn't end at your doorstep.
Living together means sharing the responsibilities and perks of the common areas. You can't use the kitchen and leave it looking like a battlefield, thinking "I'll clean it later." You have to respect the fact that others will use it after you. The same goes for the bathroom, especially during the morning rush hour.
Take it from me: respect is a two-way street. Respecting common spaces, like your shelf in the fridge or pantry, is essential. It also means respecting the habits and differences of others. Maybe your roommate is vegan, or from a different culture. Be curious, not judgmental.
Mistake #5: Underestimating the importance of the right "vibe"
This is the most subtle mistake, but perhaps the most important. You can find someone who is clean, pays on time, and is respectful, but if the "vibe" just isn't there, living together will be a drag. You don't have to become best friends, but you should be able to have a quick chat in the kitchen without feeling awkward.
The secret to a successful living situation isn't just a set of rules; it's an attitude. It's the willingness to meet each other halfway, the empathy to understand that the other person might be having a bad day, and a healthy dose of patience and humor. Sometimes, a laugh over a small domestic disaster can solve more than a thousand arguments.
When you're looking for a roommate, don't just look at their resume. Try to understand what kind of person they are. Are they positive? Open to dialogue? Willing to compromise? These are the qualities that make a difference in the long run.
So, what's the secret to finding roommates and having a harmonious life?
There's no magic formula. The real secret is getting ahead of the game. It's doing the "boring" work upfront—the questions, the rules, the honest chat—so you can enjoy a peaceful living situation later.
Think of the selection process not as a hassle, but as the first and most important investment in your peace of mind. Today, with platforms like Coinquilino, you have a ton of tools to filter people not just by the room they offer, but also by their habits and lifestyle. Use them.
Reading profiles carefully already gives you a sense of a person's "vibe." Some people write two lines, others tell their story. That alone tells you a lot.

FAQ - The questions everyone asks
### How do I handle a roommate who doesn't pay rent or bills?
This is a tough one. The first step is to talk to them immediately, and calmly, to understand if it's a temporary issue. If it persists, you need to be direct and put the deadlines in writing. Disclaimer: I'm not a lawyer, but if the situation becomes serious and their name is on the lease, you may need to consult your landlord or a legal expert to understand your options.
### What do I do if my roommate is extremely messy?
No sticky notes! Suggest a chat and agree on a minimum standard of cleanliness for the common areas. The best approach is, "I feel uncomfortable when the kitchen is like this, can we find a solution together?" Instead of accusing, you talk about how you feel. It works much better.
### Is it really a bad idea to live with a close friend?
Not necessarily, but it's a risk. If you decide to do it, you must treat the living arrangement as a "contract" separate from your friendship. Set clear rules just as you would with a stranger. Your friendship will be tested, so be prepared to communicate with brutal honesty.
### What are the 3 absolutely essential rules to establish right away?
If I had to pick just three, I'd say: 1) A clear schedule for cleaning common areas (especially the bathroom and kitchen). 2) A transparent system for managing shared expenses (a cash fund or an app). 3) A rule about guests (a simple "always give a heads-up" is enough).
### Can I kick out a problematic roommate?
It depends on the lease. If you are both on the `contratto di locazione` (lease agreement), it's very complicated and usually requires the agreement of everyone, including the landlord. If you are the primary tenant and they have a `subaffitto` (sublet agreement), you have more leverage. Disclaimer: this is a complex legal matter, so always talk to your landlord and, if necessary, an expert.

If I were you, I'd start here: before you even begin looking at places, grab a piece of paper and write down your 3 absolute non-negotiables in a roommate. Quiet after 11 PM? A high standard of cleanliness? No weekday parties? Be brutally honest with yourself.
Then, use these mental filters when you look at listings and talk to people, maybe on Coinquilino.app, where you can find lots of detailed profiles that help you understand who you're dealing with. It's free and, believe me, it'll save you a ton of hassle down the road.
