Antoine's apartment is exactly as described, very beautiful, well equipped and spacious (with a gorgeous view). We were 4 people that stayed at the apartment for 10 days and we would gladly come again. One thing to note is that the building is quite old so there is almost no sound proofing. Some of us worked remotely during the week and the noise factor might matter.
As far as communication with Antoine goes, it was absolutely great. Very responsive and helpful with everything, 100% recommend :)
