We stayed in the apartment for a week in July (extremely high season due to 14th July-Bastille Day). The apartment is located in a very convenient location - 3 min walking from RER B (direct line to CDG, app 1h ride for 10 Eur), Velobike (bike sharing-search it, it's awesome way to commute around!) station is also nearby. The apartment is well equipped and has everything we needed (Nespresso offee machine, dishwasher, washing machine, hair dryer, etc.). Although it is in the city center, it is very quiet due to being besides the building facing the street. Supermarket (Franprix) is 5-10 min walking so we quickly find everything for breakfast, and many cafes/restaurants are nearby so breakfast/lunch/dinners are easy. The building does not have an elevator, but the apartment is on the 2nd floor so it was not a problem for us. Communication with Antoine was clear and just in time. Definitely one of the best value for money that I saw in Paris at this time, so I recommend to stay there!
