We stayed at Claudia's apartment during 2015 Christmas time. The city was calm and sleepy, but the host was very warm and friendly. Our plane delayed 2 hours and we were late in the evening, but she kindly waited us. Our trip back also was late in the evening, so Claudia let us stay in the apartment till the evening without any additional charge. The flat is very bright and spacious, so our family (5 people) felt very comfortable there.
The location is also very central - 2 days we spent in Bergamo and 2 days we were traveling by train. Th train station is only 10 minutes on foot. And citta alta (old city) is also about 10-15 min on foot. And our best place for icecream (GROM) is only 4 minutes walk :) Next time we also would thing about this place to stay :) Thanks Claudia!
