Hadrien's apartment was amazing, it was cozy and pleasant, stylish and beautiful. Although it was quite a surprise to find out we stay in the last floor of a 5 stories building with no elevator. The climbing was tough after a long day, but worth it, it was a true joy to stay there. Comfortable and relaxing and the bed is large and amazing to sleep on. The best metro, line one, is right near the apartment so you get around Paris very easily.
Hadrien as a host was very helpful and nice. Highly recommend to stay there if you look for a quit place in paris.
