It was an absolute pleasure to stay in Wandrille's apartment!
Firstly, it's perfectly located at the intersection of boulevards Montmartre and Poissonier. In 3 minutes walk from the house there are supermarkets, restaurants, bars, and all stores that could be needed for your comfortable living. The nearest metro station is also in a stone's throw.
Secondly, the apartment itself is very convenient to stay, especially for the solo travelers or couples. It has fully equipped kitchen with a coffee machine, oven, and all stuff for cooking, comfortable two-leveled living space, wonderful view from the window, and calm neighbors.
Lastly, Wandrille is a perfect host who is always in touch trying to make best recommendations for your stay, and help with resolving emerging issues.
I definitely recommend Wandrille as a host and his apartment as a great place to stay in Paris.
