We were 2 adults + 2 kids. We found the place very clean and pleasant. We used the main bedroom and the kids enjoyed the big bed at the studio. The apartment is well equipped and in a walking distance for many restaurants, attractions, and the lovely old city. Public transpiration also in a distance of less than 5 min. walk. Antonio was very nice and accessible.
At night - some of the streets around the apartment may be not very pleasant (nothing extreme), but there are enough ways to avoid these streets.
