Excellent stay. This was my first time staying in the Bastille area. So many options all in walking distance. Several metro options in walking distance. The building is on a busy street but once you get in the building/unit it is super quiet, very peaceful. Jean- Christophe was very responsive from the point of booking , to check in and out. He also offers lovely suggestions of places to eat, things to do etc.
I think the space is big enough for no more than 2 people. anything more than that you will not have ample room.
Highly recommend. Will stay again during my next visit.
