The room is big and spacious, that's true.
The bed is ok, comfortable.
But honestly, this is not a very well maintained apartment.
The host is not much over the apartment and do himself. Anyway, if you need some help he tries to do his best.
There's no a door to separate the room from the rest of the apartment, but a piece of wood that you can slide in order to cover the entrance.
If you don't ask for anything else but a simple place to sleep, then it's ok.
