My colleague and I had a wonderful time at Xavier's place, in a nice family room with two separate bedrooms. We also had our own shower each, which was an additional plus. What I liked most about Xavier's place is the location, it's in Paris' most charming and beautiful quartier. The rooms was very clean and the beds very comfortable. It has all the basic needs, including a desk, chairs, and a ventilator in every room.
There is an elevator, which is often not the case in Parisian places, so very nice to not have to schlepp any heavy luggage up the stairs. I would definitely recommend to stay here and I myself hope to come stay here again some time.
