Nice place and unbeatable for the price, the Apartment is located in an urban neighborhood right next to the Mont martre, and the metro station isn't that far away either.
However, the Apartment is really small and could use some more thorough cleaning. The toilet is also separated from the room, too (which is only reachable by stairs to the highest floor).
Nonetheless, the Apartment was very, very suitable for our short stay and Charden was nice and helpful as well!
All in all, it deserves a recommendation from us, especially if you are planning to spend most of your time in the beautiful city :)
