Mario is a great host, really friendly and helpful. He kindly picked us up from the station, drove us to a supermarket and even offered to drop our stuff at the airport for us at 6.00 in the morning! He lives just upstairs so is on hand to deal with any problems, such as fixing the boiler for us, which is really great. The apartment is well equipped and a nice place to stay, quite well connected and makes a perfect base to explore the lovely city of Bergamo.
