Philippe was very helpfull upon arrival, taking time to show everything and all the necessary information regarding the place, transportation, sites, ect... He even wrote a small guidebook which is available in the appartment.
The appartment is in a perfect location in Paris, in a very quiet street, but 5 minutes walk from the butte Montmartre and the sacré coeur.
If you come to visit Paris, you will not find a better location.
