This is a perfect location. It is right next to the Basilica, Trullo Sovrano, and Ristorante La Cantina (which is probably the best restaurant experience I've ever had). It's a short walk to most other sites in Alberobello. Flavio provides a contact that meets you with the key and assists with your stay. This person is just wonderful, very responsive and gives great recommendations.
The patio is really relaxing and nice to have, though I spent most of my time out in the town. The place was very clean, the shower was great with very hot water.
Note, you can hear the bells from the Basilica, but it wasn't that loud to me. If you are a light sleeper it might wake you up.
