The flat is perfectly located in between Marais and Oberkampf. You can walk most of the time. and Metro line 5 is just in front of the door.
Also being on the top floor of the building (with elevator) and to the backside of the house, it is very quiet so that we got some sound sleep.
Hence if you are looking for a very centrally located, tidy, alas very small place, and you are on a budget, we can fully recommend Valérie´s place.
