We had a wonderful stay at Casamata! The house is in a great location in Ragusa, as well as close to Modica and Scicli.
Luigi is an awesome host! He is super communicative (via google translate) and checked in several times during our stay to make sure everything was ok. Because the house isn't accessible by car (free street parking up a couple flights of stairs), he met us in the parking area closest to the house and helped us with our luggage to the house and when we left. And, Luigi brought croissants and coffee for us on our second day.
Casamata is built into a hillside, so there are stairs and they are steep. The kitchen/living area is located on the first floor, which also has a full bathroom. The first floor has a bedroom and a full bathroom. The top floor has a bedroom only. Casamata looks just like the pictures - everything is tastefully decorated and all the appliances work. If I'm ever in Ragusa again, I would stay at Casamata!
