I stayed at Guido's place for a couple of nights as part of a girly weekend with a close friend. Communication with Guido was quick right from the point we booked. At check in, he gave us great tips on where to go, where to eat etc - all of the recommendations that we tried were great. The apartment is very clean and the beds very comfy. It is in the perfect location, easy walking distance from the Citta Alta and from the main city centre. We enjoyed fantastic food and wine during our stay in Bergamo and prices are very reasonable. I would highly recommend a stay in Bergamo and in Guido's place.
