Maybe a good proposal for those, who intends only to sleep in the room, cause it's perfectly located, and bed is comfy and big.

What I disliked (travelling with wife and 3.5 years daughter):
1. No lift! and it's 4th floor
2. Very small kitchen (3 m2). No microwave
3. Troubles with water flow and its temperature. And there wasn't even a piece of soap there (and I hardly can imagine a man travelling with his own soap)

On the other hand, if you travelling without kids, it could be ok. The app is very basic, but clean and tidy. There is a locker room downstairs, where you can leave your bags, and there is a safe with code-locker, where you can find keys for the room (so you don't even have to meet the host to enter the room). And you are literally 5 steps from tram #1 stop, and it's only 2 stations from Opera and city center. Metro is also 5 min walk
