This is a nice apartment in a great location, close to Metro stations and bus routes. We had some issues with access, cleanliness & undersupply of some of the basics (more on that below), but the positives are: reasonably priced for Paris; spacious rooms; big fridge; good TV; iron, ironing board and washing machine (but drying rack was broken); kitchen is tiny but fine; good shower. Windows are thoughtfully double glazed so in the winter months, with the windows closed, there is no traffic noise from the busy street below.
Negatives: only one thin pillow and one bath towel supplied for each person (no hand towels or face washers); nowhere to hang out wet washing; limited chinaware and some of the glasses and plates were chipped or dirty. The host was not interested in addressing these issue during our stay. His attitude was 'take it or leave it'. Hopefully these issues will be fixed for future guests because it is otherwise a good option for the area, which is outside the touristy part of Montmartre, but close enough to enjoy all the area has to offer.
