It is a cozy room where everything is at hand. Be prepared to climb to the 6th floor to enjoy the beautifull window view apartments have to offer. Though climbing would be hard for elder people.
The location is awesome: close to Monmartre cathedral (several minutes walking distance), one of the best rated Paris restaurants, metro and bus stations, shopping malls etc.
The apartments is a perfect value for the price which gives you Monmartre spirit, but if you want something more luxury this flat might be too simple.
