The apartment is super lovely and we enjoyed our stay there a lot. I didn't get to meet Guillaume in person, but the communication with him was great, he was very friendly and quick in answering any questions. We asked for a late check-out and it wasn't a problem, we really appreciated that. The neighbourhood is very vibrant and even though the building is in a loud street, we weren't bothered (the windows are on the other side). In fact we slept really well there (the mattress was amazing!!). I can definitely recommend staying there!
