The apartment is located within easy walking distance of the Duomo and train station.
The flat itself is good, and had 2 working air conditioning units, one in the living room and and one in the bedroom, which was particularly useful during our very hot stay.
Though we never got a chance to meet Gabriele, he sent a nice colleague to help us check in and he always replied promptly to my messages.
The only downside was the availability of certain kitchen items. It's not a full kitchen and we had to make do with limited utensils. There was no salt and olive oil etc which meant we had to buy our own and leave it at the end. Gabriele was kind enough to give us an umbrella during our stay though which helped.
