This apartment was in the old part of town of Modica, and only a two-minute walk from the main street. The location was excellent, and couldn't be better. There was also an excellent local Sicilian restaurant about a 1-minute walk from the apartment - ask Ornella about it. The food was fantastic, and very reasonably priced.
Ornella was a great host. She met us on the main street, and then jumped in the car with us and directed us to where to park (free). She then helped us take our luggage to the apartment, and settled us in, providing us with extra blankets (we were there for new year's eve).
The apartment itself is a spacious one-bedroom, with a couch that pulls out into a comfortable double-bed. If you go in the winter, the apartment has heating (and air conditioning) in both the living room and the bedroom. It has a lovely balcony, which can be accessed from both the living room and the bedroom. Ornella lives right upstairs, and is very helpful if there are any questions or if you need help.
I recommend this apartment to anyone - the apartment was great, and the host was great too. A truly authentic and great stay in Modica.
