Pros -
1) Convenient location, right opposite the metro station
2) The room is spacious, clean and comfortable. Has heating and extra blankets.
3) The boys who take care of the space are pretty helpful - and friendly about you using the common spaces like the kitchen and the washing machine etc.
Cons-
1) The bathroom is very, very small and not the cleanest - with multiple guests, it can get a little messy.
2) It's good to use only as a crashpad - the apartment is small and the walls are thin. You should plan to be out most of the day.
