The host: Mario was flexible and friendly to deal with. His English is limited but this was ok with the aide of Internet translator support.
The flat: Just as the pictures show. A nice size flat with good wifi, air con and a comfortable bed. The ceiling is nice and high. The cost is very reasonable.
The location: quiet, close to the duomo, free parking nearby. Ragusa is a beautiful town to stay in.
Overall: I would stay again and recommend it to others.
