Expect basic accomodation typical now of Airbnb in popular cities ie. a basic flat which has been turned into hostel-style accomodation with shared bathroom and living spaces; the host does not live in the apartment and it is not a home. If you are after a basic private room in a central location and the price is right for you then go ahead and book. If you are after hotel quality accommodation, a cozy Airbnb in someone's home or you are worried your stay may be ruined by sharing bathrooms with obnoxious guests then don't.
I was woken up early on every night of stay, the first time from a very very noisy boiler; complaints about it were met with indifference from the host. The second time I was woken was from a loud obnoxious couple who kept pressing snooze on their alarm and falling back asleep (the internal walls of the apartment let noise through) and then when I asked them to turn it off, proceeded to have very loud sex.
The pictures are quite flattering; they don't show the damp stains on the ceiling - the whole place could do with a makeover and paint job (it reminded me of a student flat). However, the room is a good size and the location is good. Have stayed in worse Airbnbs but was expecting more given the good reviews
