Me and 3 of my friends stayed one night at the Guido's place - it is worth to recommend everybody, who is going to stay in Bergamo.
- excellent view (old town and mountains!),
- good bus connection from Guido's house to the station and the old town,
- flexible arrival&departure time,
- well equipped kitchen,
- breakfast included,
- nice furniture and clean.

Moreover Guido is very helpful, he gave us maps and advices what to do.
