Dayuma's place is wonderful! It's on a closed street so no vehicles. Gorgeous and modern loft with all the necessary amenities. We really enjoyed it.
It's a little walk from the main sites (Duomo, train station) - about 20-25 minutes but it's an easy walk as long as you don't mind doing it. They have nearby bus service but we chose to walk and had no problems. Felt very safe and at home.
We liked being outside the tourist area but still close enough to things where you could walk easily. And again, the loft is very cool!
