This apartment is very close to the old city and a short (5 minute) walk to a metro stop. We stayed there with our three teenage children and it was cozy. Two of the kids slept on bunk beds in our room. The third had a day bed in a separate room. We could all squeeze around the kitchen table, but once we all sat down, you couldn’t move around the kitchen.
The building is over 300 years old. Hence its proximity to the old city and the fabulous architectural features; however, it is on the third floor and there is no elevator. Be prepared to carry any luggage up four flights of narrow stairs!
Alessandro was available via email and responded immediately. His mother lives across the hall from the apartment and was very helpful and kind - bringing us lemonade, coffee and treats.
