Luca's place is a great artsy apartment and in a very lovely building. It is very close to a supermarket, Coop.fi, a 2 minute walk maybe.
It is situated just outside of the main centre, there is a bus just by the house which can get you to the centre in about 5-10minutes. We just walked However and it only took about 30-40 minutes to walk to the duomo. Good price, relaxed host, and really good area to be.
