Me and my group stayed for a day in this place and we wouldn't recommend anyone to stay any longer. The location is just perfect but that's it. The place costs a bomb but that's just because of the location. We couldn't meet Alessia and the check in was facilitated by the housekeeper who doesn't speak English. However, that was not an issue since there was a photoalbum pointing out every basic thing needed for the stay.
The house was dusty, the mattresses were very thin and uncomfortable, towels were dirty. The bathroom had problems too - the water supply was too slow and almost no hot water after a while. The host promised a complimentary bottle of wine but that was also missing. Also, the city tax being charged here was 3.5€/person which is bit more that what is charged in other airbnbs of the city.
