Julien's studio was perfect for my week long stay in Paris. The studio is more than spacious enough for 2 people. It is well maintained and very clean. The WiFi was fast and relatively reliable. The studio includes all the amenities that you could need. The washer was a big plus and I loved the large shower. The location is close to metro stations and bus stops and is in a very nice and safe area of Paris. Plus it is around the corner from one of the best croissants in Paris so you can't beat that.
Julien was always very fast to communicate with and I had no problems getting in touch with him. He even went the extra mile to allow me a very early check-in on the day I arrived which saved me a lot of hassle. I would highly recommend his studio!
