We slept I room 19. It is a nice room in an apartment just outside the centre, but it is definitely a walkable distance. It is also very close to the metro station "florenc". The room is everything it should be for the right price! A kitchen, an hygienic bathroom and 3 separate beds (we came with 3 people and found it very nice that everyone had a bed and no one had to sleep on a sofa). The beds slept also very good. We arrived at the apartment very late (after 11pm), but this was no problem at all. The key was ready in a locker, and we could also put it back there when we left. Very convenient and not too much hassle! The only downside to the room is perhaps that in room 18, there are quite loud neighbours because they have children (I don't know if the neighbours live there permanently or if they were also guests). The children were awake early every morning and the walls are thin, so we were often woken up by them. But that is the only thing. Overall we had a very pleasant stay!!
