We had a wonderful time in Charles' appartement in Montmartre. We were welcomed by his brother Victor who was really friendly and enthousiast. The appartement is cosy and very well equiped, it had got everything you need. Near Sacre coeur in a nice neighbourhood, many stairs to climb to go to Place du Tertre though :-))
The only ging I would like is a bigger bed, though I see that wouldn't fit in the bedroom....
