This apartment is the best that we ever had in Paris! The apartment itself is really big, it has absolutely everything for a short or long stay (I stayed there with my wife for 20 days). Apartment is super comfortable and you really feel like you are at home in the apartment, which is really important for a long stay.
The location is perfect - an amazing supermarket just opposite the building and around 3-5 more supermarkets just in the 3-5min walk. Hundreds of top-rated restaurants/cafes/bakeries are also just in 2-5min walk and the metro station is also just a 1 min walk from the building. But we used metro just few times because the location is so great, that you can reach all the sightseeing places like Opera, Louvre, Jardin des Tuileries and other just in 15-20 minutes by walk.
Sam is super friendly and we will definitely stay in his apartment once again when we will be in Paris next time. Thank you so much Sam! We highly recommend this place!
