We had great time in Paris! The appartement is located in the heart of Montmartre, just next to the Sacré-Cœur . We had a very good contact with Olivier and Aline - they recommended us restaurants, drew a map etc.
The apartment is well equipped for a short stay for a couple. The only disadvantage may be the narrow stairs with the location on the top floor and really small bathroom, but it is absolutely "vrais Paris" and in a charming place ;)
