This is a well appointed clean and quiet apartment, which seems to have been renovated recently, everything very functional. It is about 10-15 minutes walk from train/bus station. Also about 5-10 minutes to via Roma, which is the main smart street of the new town. You can walk down to the old town, and there is a bus back up, if you need it. One day is ample for Ragusa as the old town is the main attraction.
Giovanni was good-natured and friendly and although he does not speak English, managed very well to explain things to us (with a bit of our basic Italian to help). The flat has a good washing machine and air-con/heating. Cooking equipment is fairly basic, but he left milk, jam, tea and coffee, condiments and some fruit - nice to be able to make a coffee on arrival.
Try da Luigi for a meal - excellent food by a passionate cook, and cheap!
