The flat is very nice and Paolo is simply delightful.

The flat is a ground-floor one bedroom off the inner courtyard, one side facing Paolo's garden. Ceilings are very high, so even though the rooms are not particularly bright, they feel quite airy. (The sitting room is an exception, as it has a loft space that partially reduces the ceiling height.) The pictures are accurate. The flat is located off the tourist trail and is quiet (except for the seagulls, which can occasionally be annoyingly loud at night). That said, it is easy to get to the things you want to see.
Paolo was extremely helpful. When we arrived, he met us at the Vaparetto, then showed us around the neighborhood and made suggestions as to where to get fruit & veg, coffee, a drink, an ice cream, dinner. He was very willing to call or visit the restaurant and make reservations for us, which was great. The administrative tasks around the flat all went smoothly and pleasantly.
All in all, we had a very positive experience.
