I and family have enjoyed staying in Massi & Emilio flat. It is big, very nicely decorated and very comfortable for 4-5 people. I was amazed by the table serving prepared for us, it was a great surprise from hosts and a truly warm welcome.
The apartment is located close to the old town, in a very nice area with nice trattorias and enotecas to enjoy local treats. You can also easily navigate by car between Milan, Como lake and Bergamo airport. Very much recommended as a place to stay in Bergamo.
