Julien's place is one of the most cozy, stylish and Parisian looking spaces I've ever stayed in. We were four of us and were looking for a good value 2 bedroom apartment in a good area, and Julien's place was the best choice. About 45 minutes from city center by foot (we were in Paris during the metro strike), but a lovely walk through nice neighbourhoods. Very close to Gare du Nord, so convenient for reaching the airport back. Very easy and fluent communication, we got in and out of the apartment by ourselves, with a key, and the flexible checkin time was great for us, since we arrived a bit early.
Couldn't be more pleased with having chosen Julien's place for my parents' first time in Paris.
