I highly recommend staying at Andrea's place. First of all it's in an amazing setting of a beautiful and historic palazzo. The large room we were staying in, with an exquisite ceiling, had a great ambience.
It's centrally located within easy walking distance from the train station and the funicular station that goes to the Citta Alta old part of Bergamo. There's a large grocery store less than a block away if you want to make your meals in the well-equipped kitchen available for your use. Alternatively, there are restaurants nearby. (The local bus stop is also nearby.) Andrea makes breakfast surprise treats for the guests which are absolutely delicious.
We can't thank Andrea enough for rushing our daughter and us to emergency at the hospital when she experienced a severe allergic reaction to nuts. He waited at the hospital with us during the entire time that our daughter was at the hospital and checked in with us afterwards to make sure she was ok. Thank you to Django and Blue (the dogs) for waiting patiently in the car while we were at the hospital. And thanks to Andrea's girlfriend who helped us with getting the medications that our daughter needed after her allergic ordeal.
So aside from running an excellent and unique place for travellers, Andrea went far beyond the call of duty to help a family in need - he's a great guy and true superhost.
