We really liked staying in Alice and Juliette's flat. The location is great- right in the middle of Montmartre, very close to the Metro and about a 30-50 minute walk to lots of places of interest. It's close to bars, coffee shops, supermarkets and restaurants, and it's a lovely place to stay. It's on the 6th floor which might be a concern for some but if stairs don't phase you it's fine!
