The flat is really well located, in a calm and safe neighbourhood. It is confortable, well-equipped and super quiet. You have everything you need at close hand (metro, RER, supermarket, etc.).
Fan is a very attentionate host, who kept in touch during our stay and answered quickly to any question. But he wasn't there for the chek-in and we had to deal with the housemaid who didn't speak english nor french. We arrived lately but she hadn't started cleaning the flat and kept eating her lunch while we dropped our stuff... Except that weird welcoming, everything went just fine!
