I had a great stay at Guilia's apartment. She was very easy to communicate with and even sent me a little list of local places to eat, organized my airport taxi and left me a bottle of wine!
I was traveling alone and felt very safe in the neighborhood and the building. Plus it was central enough to walk to all the major attractions but far enough away that you felt like a local. And there are some great places to eat only a few yards away! I would definitely stay here again!
