Me and my family stayed at Marcello's house for one night. It's a perfect location if you drive from the airport by car, you can park the car in the neighborhood for free and then go to the central Bergamo by bus (the stop is very close to the house). Marcello and his wife were very kind and accommodating. Although we arrived late at night (1 hour later than agreed initially), they met us in person and shown us around the apartment. The apartment itself is nice and clean. Highly recommended!
