We booked for four people but it was small even for three. Anyway, we only needed to stay there for sleeping, so it wasn't a big problem.
Then, the wi-fi connection worked without problems, it i close to Gare de Lyon and Bastille, so it's easy to move around the city by public transport (and it's not suggested to visit Paris on foot). There are also a lot of shops and restaurants around, in case of every needing.
