Our stay with FAWZI was great. The location very close to the Saint Martin canal, Place de la Republique and the proximity to the metro line was spectacular. Very easy to find everything you need in the neighborhood such as pharmacy, restaurants, bakeries, etc.
The bathroom is very complete and the "small but great" piece of life for a few days. My only criticism is for the comfort of the mattress which is very thin and if you need to "rest" it can get complicated. If it's just a quick pass, that's fine. Still I recommend Fawzi's place to everyone :)
