Our stay in the flat went well overall. The flat was bigger than we expected, beautiful, well arranged and globally clean. Its location is fine to access the historical centre on foot, but far from the port and the sea-side, for which taking the bus or the metro is possible.
We had some troubles checking-in, and had to wait around 1 hour even if our hosts did their best to send someone to open a door which had been locked by mistake. We were 6 and one bed was missing, but we could arrange with our hosts getting another one in the flat they own right next to ours. We didn't see our hosts during our stay : check-in and check-out were to be done on our own.
