Julien's seventh heaven is defenitely worth a stay. Though it's not that easy to reach, (there is plenty of doors and stairs to overcome), once you are in the little flat you feel really into Paris and its lifestyle. There is everything you need for a short stay in beautiful Paris, the metro is located right next to the main door and the quarter is also very parisien. The communication with Julien was great and I would love to come back one day!
