We were three young women sharing this space with no problem. It is nice and personal flat in a wonderful old building and has very comfortable beds, an amazing balcony with excellent views (to the top of the Bastill monument!) and Paris charm and ambiance.
No wifi, no elevator, in case you mind.
Sheets were provided (and a king duvet and a sleeping bag) but no towels.
Excellent location, can't go wrong with that.
