The apartment is really small, especially the bathroom, as written in the description. It's a good solution if you are planning to stay all day out in Paris. The neighborhood is quite, but it's not super comfortable to reach the apartment if you have heavy luggage, since Montmartre is uphill and the flat is one the 3rd floor with very steep stairs.
We had an inconvenience with the cleaning of the apartment, but Fralma was very responsive and quickly solved the issue.
