We stayed here for 4 nights at the end of Sept/ beg of Oct. We really loved the location of the hotel. It was well connected to the city, only a couple of minutes walk from the Vaugirard metro station. It was a nice quiet residential neighbourhood which was nice given how hectic the city centre can get. Close by there are many restaurants, boulangeries, grocery stores. If you don't mind a walk, you can still walk to some sights. We walked to the Eiffel Tower and the Musee de L'armee.
The rooms were very small, the smallest I've stayed in for sure. But they are stylish, clean, air conditioned and have the best shower of all of the places we stayed. The bed was extremely comfortable. I have seen some complaints about the wifi, but we had great connections the whole time we were there, even the evening when we were warned by the front desk that the connection was slow. Like many of the other reviewers, we didn't try the breakfast, opting instead for the patisserie next door.
