Edoardo e Giuseppa's place is a really lovely, quaint little house on a spectacularly beautiful property about 20-30 minutes walking from the beach. You definitely need a car to get to and from the property, though. It is about a half an hour from Ortigia, so if you want to visit the city, you'll need a car, too.
Important considerations are: One of the bedrooms is adjoined with the kitchen and only separated by a small divider, not a wall. Likewise, the doors (to the bathroom and other bedroom) are accordion-type doors that are quite noisy, so if you are a light sleeper, I would recommend bringing earplugs as to not get woken up if the person in the second bedroom has to go pee in the middle of the night. Also, the listing says there is a washing machine on the property, but it's part of the main house, so you must make a special request to the residents (Edoardo e Giuseppa) to use it.
Their dog is an absolute peach; he is such a big-hearted sweetheart and will greet you if you come home at night, which made us feel very safe.
