This was a great apartment for us to visit Bergamo for a night. It is perfectly situated in the Citta Alta, just a block or two from the main road. The only struggle was trying to park in the tiny street (I recommend giving up and parking a few blocks away on Via Della Boccola unless you are comfortable with old Italian roads). Once we were parked, though, everything was just a few minutes away on foot!
The flat was really cool too. It looks like it's mostly the original stone for the building, so you really get the feeling of living in the old town. It has a cool little kitchen-in-a-cupboard which was surprisingly versatile. Not sure how it would work for several nights, but for a quick trip it had everything we needed!
