We spent 3 great days at Nicola & Chiara's place. The description is perfectly correct: the flat is step away from the Duomo. So it was very easy to arrive early to visit and avoid queueing. Everything is very convenient : the flat is fully furnished, clean, safe, There are many nice restaurants close by.
The contact with our hosts was very smooth : although we arrived late at night, it was no probem and Nicola greated us on arrival. We exchange sms to decide the departure time. All very simple.
The only inconvenient of the flat is the noise at night during week days (early deliveries). We recommand you having some ear plugs.
We definitely recommand this place and will return as soon as we can.
