Pilar's flat location is just fantastic - right in the heart of Citta Alta, in a bucolic street in medieval Bergamo, easily accessible by funicular and a short walk from the bus stop.
The apartment itself, while not being big, is perfectly comfortable and suitable for shorter stays, and is very bright and airy. It was spotlessly clean, and featured a small kitchenette for quicker meals - being Italy you'll want to eat out so the space is perfectly adequate for a quick snack.
Shower was good and there was plenty of hot water.
Communication with Pilar was extremely easy as she lives in the same building. As a host Pilar was excellent and very accommodating.
WiFi signal was a bit weak at times as the router is not in the flat, but just served as an incentive to go out and explore the city.
