It was our second stay in Enrico's appartment. Everything was neat, warm, well-thought. I often go to Bergamo, and I really like this one. Not too expensive and very well located. You can also really cook if you don't plan on going to a restaurant for every meal.
What's more, we had a little delay at the moment of departure, and Enrico was really nice about it.
The negative points: thin walls with the neighours (but this time it never bothered us and we slept like a rock) and a mattress that is not too comfortable, especially on the right side (towards the door).
