This was our location for our first two nights in Paris, and next time I'll stay longer. Hotel Des Arts is a wonderful hotel with an excellent staff. The location allowed us to explore all that Montmartre had to offer and come back for a very comfortable night in our cozy sixth-floor room with a view of Sacré-Cœur over Paris rooftops. We also had the full moon on view from our window, but I don't think the hotel arranged that :-)
We enjoyed the complementary glasses of champagne, but, really, we just loved the art-focused interior; the professional, polite, and accommodating staff; and proximity to cafes, boulangeries, and Basilique du Sacré-Cœur de Montmartre.
