The location is great for going to museums and exploring Paris. The apartment was convenient for us; I used the bed in the bedroom and my friend slept on the couch in the living room; the beds were comfortable. The living room was over a restaurant and there was some noise as they set it up in the morning; I did not hear that in the bedroom. The weather in December was not pleasant and the stone floor was cold despite adequate heating; for winter months one needs bedroom shoes with a thick sole. We dealt with George who was very helpful and patient with us when we pestered him with questions. It would be helpful if there were an info sheet. In other places I stayed there were some supplies: tea, coffee, salt, sugar, olive oil. Here we had to get all that ourselves. Also, the spiral staircase to the 3d floor was a bit of a challenge.
Anyway, on balance it was a lovely place and we enjoyed our stay!
