I highly recommend CityWalls Guest House in Bergamo. Simone is very communicative and I have always received response in a few minutes. Location - near to the city centre, old town and nice coffee/drink house 1 minute away. The flat was super clean and tidy. Beds were also very comfortable. There is also a small balcony. For breakfast we got croissants, juice, toasts, yoghurt and coffee - all fresh and tasty. We regret, that we did not stay here for longer.
