The location of Camille's flat is perfect about 2 minutes from the metro, 2 stops from Gare de l'Est a few from all major attractions, there's a vegan burger place and a supermarket just around the corner, etc. Although she wasn't there at the time, communication with Camille was very nice and her replies were prompt and helpful. Check ins and check outs were extremely flexible.
The flat itself has a student-ish charm, it's very pretty with nice wood floors, etc. The kitchen is a bit overloaded, but has everything you need. The main downside that might make you consider the place is the toilet, which is in a super small cubicle separate from the bathroom with no garbage container or sink and whose door is a bit of a pain to get to close and lock. Other than that I can highly recommend Camille's place and especially Camille as a host.
