Casa Orni was wonderful! The view from the balkony is amazing, especially at night when the orange ligths illuminate the old town in a fiery shade.
Ornella was perfectly helpful and communication (text/whatsapp/mail) was always easy and rapidly answered. She told us that a friendly neighbor who loves cooking would prepare a meal for us if we asked her - but that wasn't even necessary since she just came over to bring us delicious various italian meals!
Ornella's selfmade travel guide for Modica and surroundings was really useful. We actually used almost only that one since the one we bought was a bit crappy ;)
The location of Casa Orni is great - but be prepared to climb some steps down to the main road Corso Umberto and a lot more up to to the old town center. It's kind of a workout, we really enjoyed it :)

Two thumbs up for Ornella and her Casa Orni - a top host and top accomodation!
