Best Value! In & out in 2 days, solo traveling, no negative issues, 100% functional. What you are paying is: location + a clean and functional room.
Being on the top floor and the lack of elevator may be an issue for some people, but if you are traveling thru Europe, I suppose you are in good/decent physical shape. If you need elevator to go up 4 floors, this is NOT for you. Everybody else, this hotel is everything you need for 3 nights in Paris if you want to be in the Montmartre area and well connected via Metro. Pigalle metro station is 2 minutes walk, Abbesses station 4 minutes.
It is clean, location is excellent, and the WiFi is better than most 3-star hotels in the U.S. There is one guy at the front desk in case you need assistance. Don't forget to visit Bouillon Pigalle restaurant right around the corner: best value, local food, low prices and they are open late. There is a line of people waiting... you will not be disappointed.
