Except for the six flights of stairs you must climb, Julian's home has everything a solo traveler could ever want and it's in one of the most popular locations in Paris, right above the Rambuteau metro stop and just a block down from the Pompidou center in The Marais district.
Julien is a successful filmmaker and the space is stylishly designed around a cinema theme, complete with a remote that slowly dims the lights off before starting a movie. It's like a studio combination home theater.
I highly recommend Julien's place for people who know Paris and want to be centrally located and near a lot of shops and restaurants.
