Giovanni was fantastic! He was great about getting back to us promptly about the rental. When we arrived, he was so gracious to let us in a bit early, and then gave us several tips for navigating the area, sights to see, and restaurants to try (definitely try Sorbillo). He was wonderful to deal with.
As for the rental, it's in a college area so the evenings definitely are busy and lively in the evening, but the apartment is behind a locked gate and so the nightlife isn't intrusive. The flat itself is very clean and inviting. We would definitely stay here again if we were in the area!
