My wife and I spent four nights in the Celine apartment and found it to be perfect for us.We have rented apartments in Montmartre on four different trips, but Celine is easily our favorite. It is spacious, well equipped, stylishly decorated with furniture, art, and odd pieces from all over the world. It is cheerfully painted in bright colors. The views are spectacular from all rooms, and ending a day in the comfort of the living room with its views over Paris and a glass (or more) of wine, was one of our favorite parts of the vacation. The location is perfect--quiet, but easy walks to the Metro, Place du Tertres, and the shops and cafes of Rue des Abbesses. A walk down to Grenier du Pain for croissants and a baguette is a perfect way to begin the day. Nice building, just a beautiful place to hang out. Almost as a bonus, the Coq au Rico on the corner is one of the better bistros in the city
I do think that InBeau should make the check in/out process easier. There are 4 pages of instructions, and I'll leave it at that. Apart from that minor quibble, the place is perfect. You won't be sorry if you rent it.
