Relais Parco Cavalonga was the second of our two bases for our short-ish (8 days, short for Sicily) trip to Sicily. We used it to explore Noto, Siracusa, and other nearby attractions. As with our other accommodation, we asked Relais to help us with a last-minute date change because of our son's last-minute illness, and they were able to do so. Additionally, we had a miscommunication at the last minute about our total bill, as we were staying one less day than we had originally booked. Relais, even though it was wholly reasonable to us (this occurred literally as we were checking out) that they ask us for the amount that we originally agreed to, refused to accept that amount, and refunded us for a day. In other words, the Relais staff are, as others have said, very kind, helpful and go out of their way to help guests have an enjoyable stay.
We stayed in the Donnafugata suite, which includes a good-sized living and dining room, a full kitchen (with a full-size fridge) a large master bedroom and ensuite bathroom, and a smaller second bedroom with ensuite bathroom. The suite was a very good value, and we would stay here again. We especially appreciated having access to our own kitchen and laundry.
The only issues we had were with some tiny ants coming in in the mornings looking for meal leftovers (it's a good idea to, if you have children especially, make sure the dining table and floor are totally clean after meals), which is really a very minor problem, and resolving our magical ability to lock the door to the dining room. Otherwise we were very pleased.
