Guido's apartement is in a perfect location to visit Bergamo.. it is still in Citta Basa so expect to climb a few stairs before getting to the old town but having said that it is around the corner from the Academia Carrara and GAMEC so not a bad location at all. And above a fantastic gelateria, and close to an amazing park if you have children. Guido's communication was excellent and he was very helpful in dealing with a problem we had in the apartment during our stay
