This is a nice place near the center of the city. Plenty of access to all of the things that a traveler needs, and within walking distance to the train station and La Cita Alta, the primary tourist spot in Bergamo.
The accommodations themselves were very reasonable. Andrea took the time to point out the important aspects of the city on a map to me on arrival. My room was large and the bed was comfortable. The only critical thing that I can add is that Andrea rents out 3 of the four rooms in his flat to other Airbnbers. It's not necessarily a bad thing, but I didn't know before I arrived. I was there for an extended weekend and shared the common areas with ~8 different people over that time. It was pretty hectic and made it hard to feel settled, but it was also good for meeting new folks.
