Antonio's place is great - it is nicely decorated and fully equipped. It feels like somebody is actually living there and not like a hotel room :) The small balcony and the big patio were really great!
The apartment is located about 10-15 minutes away from most interesting things in the center. There are many good local restaurants very close to it. It is located in the ZTL, but it was very easy to handle - you can buy a daily pass for 5 euros and finding a parking space in front of it was always very easy.
Antonio was very helpful the whole time during our stay - he gave us many recommendations and helped us a lot with the ZTL. He his really a great host!
