Guillaume's assistance during our stay in the apartment was great.
The problem we faced was the bed location, because it must be reached with a ladder. That is not very comfortable and one must be very careful, especially when it's necessary to use the restroom at night.
Apart from that, the apartment location is really great, in one of the best Paris neighborhoods. Guillaume's promptness and efficiency to solve some issues we faced in the first day was remarkable. The apartment is really cozy and has a little kitchen. You can buy some cheese, bread and wine, for instance, and have a nice dinner there.
