The hosts were very kind and even agreed to meet us late to open the apartment.
It is a very nice little apartment that is very near the metro and other restaurants and a few small grocery stores.
The only drawback was the noise from all of the restaurants below. We had to shut the windows which was unfortunate in the really unusually hot temperatures we had in Paris during our stay.
I would still recommend this place, especially if you like to go out a lot.
