The apartment is nice and spacious. The location is great - you can easily explore lower city on foot (there are few lovely bars and cafes just outside the apartment) and it takes 15/20 minutes on foot to get to the funicolare station. You can also walk to the city alta directly if you don't mind walking uphill. However, the most special thing about our stay in this apartment were interactions with Flavio - he's a lovely host, he greeted us in person, agreed to hold our luggage till the evening and provided us with a lovely guide to Bergamo. He also called the police when one of us lost our wallet.
