Actually we generally like Ragusa. However, it really can not be recommended unless you have a car, or are in great shape. I arrived via bus, walked to hotel - sorta on the way to new city center - then to the old city, and back to the hotel. My phone registered 22,000+ steps, and climbing 30 flights of stairs for the day - that was all Ragusa. Another indicator is the pain in my feet.
There are other places where the train station to the city center is very close - some examples are Polignano a Mare, Sorrento, Rome, etc. Places like Milan have a good subway to whisk you around.
Ragusa has some primitive bus service (AST company) but locals say its totally unreliable. A taxi from hotel to new city center is 15 eu each way. There are some scooters but didn't want to break our necks.
Modica is not much better. Scicle is pretty good - but thats another set of problems.
