We stayed in this flat for 4 nights. The hosts were welcoming and helpful. The flat is on the small side, I would say it is more enjoyable by a couple than by a family (we are a family of 3), because if you open the sofa bed in the living room, it occupies most of the space in the room, and you need to move the table and chairs every time.
The location of the flat is fantastic, right in the old centre and close to all the main tourist attractions and to a lot of bars and restaurants. Despite being so central, the flat is also quiet thanks to the double windows.
