How to Actually Find a Roommate in Prague (Without Losing Your Mind)

If you've ever tried to find a roommate in Prague, you know the rhythm.

You join four Facebook groups. You scroll past 30 posts that aren't actually about housing. You finally find one that looks promising. You send a DM. Five days later they reply, but they've already found someone. You go back to scrolling.

By week three you're not picky about the flat anymore. You're picky about not losing your mind.

This is the part of moving to Prague that nobody warns you about. Finding a flat in 2026 takes about a week. Finding a roommate who doesn't drive you out of it takes longer, and the platforms most people use are actively making it harder.

Why it's harder than ever

Prague's rental market is split into two: studios you live in alone, and 2-3-4+kk flats you share. In central Prague, sharing is the only way most people under 30 can afford a real apartment. Solo studios in Vinohrady run 18,000 CZK and up. A 3+kk in the same neighborhood runs 32,000 to 40,000, so split between three people it works out to about 12,000 CZK each. That math is what drives roommate culture here.

But the platforms where you find roommates are all built for finding flats. They list properties, not people. So you end up sifting through Looking for roommate, 1 spot, 12,000 CZK, message me posts that tell you nothing about the person you'd be living with.

The information you actually need is buried somewhere in private messages. And usually the person you're chatting with stops responding the moment they hear from someone else.

Where people look (and what's wrong with each)

Facebook groups

The biggest ones are Expats in Prague, Prague Housing & Flat Sharing, Foreigners in Prague, and Internations Prague Housing. Each has tens of thousands of members.

What's good about them: they're free, they're active, and you can read someone's profile before you meet them.

What's bad about them: every post triggers 40 DMs in the first hour. The poster reads three of them. You never know if you're number 4 or number 25 in the queue. Scammers post the same fake flat across all four groups daily. And most conversations end up in Messenger, which means you can't search them, can't filter, and can't keep things organised.

If you're going to use Facebook groups, the trick is to BE the poster, not the responder. Write a clear post about what you're looking for. Pin one good photo of yourself. Include your budget range, neighborhoods you'd consider, and three specific facts about how you live (work hours, cleaning habits, guests). You'll get fewer responses, but they'll be much better targeted.

Bazoš

Bazoš is Czech Craigslist. It works for finding flats but the roommate section is mostly people who don't speak English, plus a high concentration of scam listings. If your Czech is solid, it's worth checking. If not, skip.

Bezrealitky and Sreality

Both have a spolubydlení (roommate) section. They're better moderated than Facebook but the listings are still flat-first. You're applying to live in a specific room in someone's flat, not matching with a person. If you like the flat and the existing roommates are friendly, great. If not, you're stuck unless you move.

Reddit (r/prague, r/expats_in_czechia)

Smaller pool. The signal-to-noise is better than Facebook, but the volume is low. You might see two or three relevant posts a week. Worth subscribing to as a backup. Don't rely on it as your main channel.

Word of mouth

The single highest-quality way to find a roommate. If you have any friends or coworkers in Prague, ask them. People who already know you can vouch for what you're like to live with, which is the information that actually matters. The downside is timing: you find roommates this way when they're available, not when you need them.

The questions you actually need to ask

Most roommate conversations fail because both sides ask the wrong things. Do you smoke? tells you almost nothing. What time do you usually go to bed? tells you a lot.

Here are the questions worth asking before you agree to share a flat with someone. Adapt the wording, but cover the topics:

• What are your work hours? Are you in the flat during the day or out?
• What's a normal evening for you? Cooking, having people over, going out?
• How clean do you keep shared spaces? Do you wash dishes immediately or pile them for the day?
• Do you have guests over often? Overnight guests on weekends?
• Are you a morning person or an evening person?
• How do you handle disagreements? Do you say things directly or wait until it builds up?
• Do you cook for yourself or eat out?
• Are you OK with pets in the flat? Do you have any?
• What kind of noise level do you keep on weeknights? On weekends?
• How long are you planning to stay in the flat?

If their answers don't match yours on more than two of these, the living situation is going to have friction. It might still be workable, but you should know going in.

Red flags in roommate responses

A few patterns that should make you pause:

• Vague answers to specific questions. I'm easygoing about everything is not an answer about cleaning. It's a way to avoid the topic.
• Refusing to do a video call before signing. If you're moving from another country, this is non-negotiable. You don't sign a contract with someone you haven't seen.
• Pushing for quick commitment. I have three other people interested, can you decide by tomorrow? Sometimes true, often manufactured urgency.
• Reluctance to share the rent breakdown. If you're paying for half of a flat, you need to see the full nájem and energie split.
• They want all communication on WhatsApp or Telegram only and refuse to send anything in writing about the arrangement.

A simple screening process

If you have one or two strong candidates, here's a sequence that filters most of the bad fits:

1. Exchange messages. Cover the questions above. Should take 30 minutes of writing time total.
2. Do a 20-minute video call. Camera on. You're not interviewing them, you're seeing if you'd want them in your kitchen at 8 AM.
3. If both still feel right, meet in person at a café (not at the flat). Coffee, an hour, casual.
4. If you still want to move forward, do the flat viewing together.
5. Before signing anything, agree in writing on the basics: who's on the lease, how rent and bills are split, how the deposit is handled, how notice works.

Most failures happen because people skip steps 2 and 5. The video call catches incompatibilities you can't tell from text. The written agreement catches the misunderstandings nobody wants to have later.

The thing nobody fixed

The whole reason this is hard: every existing platform optimises for matching you with a flat, not with a person. You answer questions about budget and neighborhood. You don't answer questions about how you actually live.

That's the gap DomuHQ exists to close. Our matching algorithm runs on lifestyle and personality compatibility first, then surfaces the flats that work for the matches you already have. You answer over 100 questions across cleaning habits, schedule, social rhythm, communication style, and how you handle conflict. Daily lifestyle carries the most weight, because it causes the most conflict, followed by personality, then values, then interests and concrete preferences.

It's the inverse of how Facebook groups work. Instead of starting with here's a flat, find a person, it starts with here's a person you'd actually want to live with, here are the flats you can take together.

The pain of finding the right roommate in Prague is real and the city specifically has it bad. The good news is the math works once you find one. About 12,000 CZK a month in Vinohrady, split fairly, with someone you don't dread coming home to. That's the goal worth holding out for.
