We stayed three nights at the appartement and we had a great time. Alex was really friendly and helpfull and tried to make everything comfortable. The flat was well equipped and clean. Even though the surrounding was quite busy the nights were quite. One negative point is that the room was very bright during the night because of the street lamps. So if you are sensitive bring a sleep mask.
Anyway, I would recommend this flat to everyone who wants to discover the city as much as possible!
