Gregoire's place is in an excellent location - so central you can walk everywhere and a great neighbourhood with cool bars and cafes. Communication was great - I didn't actually meet Gregoire but he organised for his flatmate to let me in and show me around. The apartment is clean and tidy and comfortable. the only thing was that I wasn't aware someone would be sleeping in the living room every night, so if you feel uncomfortable walking through someone's bedroom to get to the bathroom at night or to the kitchen for a glass of water, it might not be for you.
