This is a lovely, quite spacious flat, spotlessly clean, with great views, and a beautiful living room. It has a wonderful location (near the Porta Sant'Agostino, a short walk or very short 'bus journey into the centre of the città alta). The kitchen is a bit spartan (but there are so many good and reasonably-priced places to eat in Bergamo it doesn't really matter). One warning: the bathroom is under a very sharply sloping roof. Anyone over about 5'9" risks smashing their head on a steel beam as they rise from wc or bidet. I had stayed in the same flat some years ago, when Bergamo-resident friends of mine used to rent it, and smashed my head hard then. I did the same (twice) this time. The bathroom itself is well-appointed and charming but if you are 6' and stupid (like me) you have been warned.
The check in and check out procedure could not have been simpler. The owner is really helpful.
