Nicola has been from the beginning a friendly and comprehensive host. He tried his best to welcome us, even to pick us up at the Bergamo airport !
The flat can receive 5 people without problem, and his located just beside a pedestrian street which is full of nice bars in the evening. It was also easy to reach Duomo with the tram.
The wi-fi didn't work this week-end, otherwise I would have given a 5 stars instead of 4. So don't hesitate, book it !
