I stayed at Montmartre - Beau duplex avec vue Sacré-cœur for four nights. The apartment was quiet, sunny, very clean, and there was a wonderful view of Sacre Coeur from the bedroom. The hosts were kind and responsive. The location was very close to the Metro and only 10 min walk from Sacre Coeur. The apartment is on the 5th floor so be prepared to carry your luggage up the stairs, but this also gives the apartment the great view. I would definately stay here again.
