We were 4 people in the apartment and had a wonderful time. The living space is large enough to comfortably sit and eat together, if you're not out in Paris choosing one of many good Restaurants/Cafés in the vicinity. (The wash rooms are very small - for larger travelers - though they thus give more living space in return.)
The communication was good, quick and personal. The apartment has a nice character and transports a relaxed and welcoming atmosphere. All in all a beautiful and well situated apartment.
