Advantages:
Quite close to the center of Paris.
Disadvantages:
1. The room space is quite small, with a short height, and as for the bathroom, it has a very very small sink. The shower and the W. C are OK.
2. It is sited in a very "busy" and therefore noisy location, hearing quarels almost every night! The windows weren't soundproof at all.
3. During our stay, there was an electricity problem and 3 sockets at one of the walls were off. "Room4me" offered to help, but they didn't have a second key and we didn't leave ours.
4. We were 4 people, and we found 2 pillows.
