Alice was very friendly, always in contact, and gave us all instructions on how to get the keys, so we were not restricted in time and could explore Bergamo city at our own pace. An important note to fellow travelers: via G. Marconi is a very common street name in Italy, so make sure you also write the name of the village (Costa di Mezzate), otherwise, you'll end up like us, arriving in the wrong village at the same address. Luckily, Alice responded promptly on the phone and sent us help when we were stuck in the middle of nowhere with a low battery on the phone :) A million thanks for that!
The place was clean and cozy and had an amazing location, close to a bridge and river. It also was very warm inside, which is important when you're travelling off-season :)
We had the most magical morning walking 10 minutes to the castle and having an amazing breakfast in gelateria nearby :)
