Fantastic location - 15-min walk to Duomo; close to the new beautifully done Starbucks outlet which is supposedly one of the prettiest in the world; a lot of amenities, restaurants, shops & bakeries. The unit faces a main road, so you can hear cars passing by in the day, but I slept just fine at night.
The host was extremely helpful & reassuring - very responsive in replying messages throughout the day, accommodative for various requests.
