Small but okay. Good price, especially given the location. Walls are however paper thin, one of the bedrooms has no windows, you can’t breathe if you don’t sleep with the doors open, the beds barely fit in the rooms from wall to wall so not great for tall people. The neighbours upstairs and in the next door apartment were extremely loud, the apartment upstairs was partying until 5 AM. Which is alright on a Friday night but still a bit annoying after a few hours ;)
The walls in the bedroom without windows seemed to have some mould or some similar stains. Otherwise it was alright, especially for that price - can’t really complain for Paris and that location.
