We stayed here for a week on our 30th anniversary. We enjoyed it very much. The space seems recently remodeled and was very nice and clean. The Montmartre area is very touristy (since we were tourists we liked this) with lost of shops, restaurants, and the Sacre Couer church with a great view of Paris from the top of the dome.
There are so many restaurants it would be hard to choose, but the apartment book had recommendations and all of them were excellent.
The apartment is 3 floors up a narrow steep winding staircase, with no elevator. So be prepared for that. The bed is in a loft above the kitchen up some more steep stairs. The loft roof slopes down toward the foot of the bed, so you have to duck a lot to walk by the foot of the bed.
