The flat is vey good located. Within max. 20 walking minutes you're at the Duomo in the centre. The area was great as well. It was not dead, but neither noisy. To get there from the airport was super simple as Lorenzo gave us all bus information in advance.
The flat itself is great, too. It provided everything we needed and Lorenzo and his girlfriend Irene were super welcoming and warm-hearted. The offered us breakfast, gave us some advices for sightseeing and restaurants and we even went for some drinks together. If you look for some great Italian experience, I truly recommend staying in their flat :-)
