First of all, Laura is a lovely woman. She did everything she could to make us feel at home, she was very helpfull. Tasty things in the fridge and a very warm welcome. The apartment itself is large, spacious and fully equipped. The beds are comfortable. You can reach the Duomo in 5-10 minutes on foot. I highly recommend this apartment!
(Just one tip, be sure to beware of ZTL zone if you are by car, but don't let it be a reason not to go there!)
