This place is a real gem for our second trip to Paris. Location is near the heart of Montmartre and it has nice amenities, such as an elevator, dishwasher, washer AND dryer. The bedroom faces a busy street but there are metal shutters that are good at blocking out street noise. When all of the windows are open, the cross-breeze is really refreshing.
One thing I should note is that the Montmartre area, and the two Metro stops convenient to the area (Abbesses and Caulaincourt) have MANY stairs, which would be an issue if you have a lot of baggage and/or if mobility is a problem. The two Metro stops do have elevators, but you will still need to take stairs to the place most likely.
If you are prepared to walk a lot and would enjoy getting lost in Paris, this is a great option.
