Julien was an excellent host. He contacted us inmediately after we expressed interested and he reached out and offered to call to give me directions to get to his place and answer any questions. His apartment was great. He has a beautiful studio in Montmartre, right by the Sacre Coeur. It has great light, since it is a 6th floor and it has an elevator (something rare in Paris and so uselful after a day walking non-stop). The bed is súper confortable and so is the couch. From the balcony you can see the Sacre Coeur. It is súper quiet since the balcony faces an interior patio.
Since he was travelling upon our arrival, he gave the keys to the doorwoman who was extremly nice and helpful. He left us a nice letter with recommendations on what to do in the área and a map. We had a great stay and are very grateful.
