We aimed to stay at the southeastern tip of Sicily to enjoy beaches distant from crowded tourist places. Roberto's accommodation turned out to be the ideal solution.
The place consists of a small kitchen, a bedroom and a bathroom. The house is in a calm area, literally 3 minutes walking distance to the beach. It seems to have 3 apartments overall, of which two are offered for rent here on Airbnb. The third one is inhabited by Roberto's parents, who will be your factual hosts, guided by Roberto's contact via phone.
As most of the other reviewers already pointed out, Roberto's parents are nice and caring hosts, who will make sure you will get everything needed to have your stay as comfortable as possible.
We felt a bit ignorant when realizing that we didn't prepare ourselves for any language barrier and didn't even have any Italian phrase book at hand. Luckily Roberto's parents had some German skills, otherwise we would have had a hard time to explain ourselves.
Surprisingly even tourist orientated businesses like car rentals, hotels or attractions like wildlife parks or museums noticeably aren't prepared for international guests so much and quite often personnel lacks sufficient English capabilities to serve even basic touristic needs conveniently. Of course I would agree that for a longer stay it would deem not only polite but appropriate for the traveler to prepare some language knowledge to get in touch with the local population of his destination.

I would recommend Roberto's place to everyone interested to enjoy some timeout in a remote area. You will be able to relax there and no one is going to find you :)
If you aim to see more of Sicily's south instead, I would rather recommend to stay north and west of the SS115 road, as infrastructure seems to be more dense there. Also you will notice that the closer you get to the southeastern tip, the more you will face sad looking formerly nice but now abandoned estates, sadly accompanied by a never ending belt of ever present domestic waste alongside the streets. Though this won't be any problem as long as you aim to stay at the calm and beautiful beaches next to Robertos place.

If you arrive on Sundays - like we did - bring some food with you. There won't be any open shops on Sundays and if Roberto's parents wouldn't have provided us with basic ingredients as a welcoming gift, which enabled us to prepare a simple but tasteful Italian meal, we would have had the choice between starvation or a minimum 40 km ride to the next McDonalds in Ragusa or Syracusa.

We had a nice informative week there enjoying the coastline, baroque town centers in Ragusa, Noto and Syracusa (deserve a day trip each) and some traces of the Allied landing on Sicily in 1943.

Thank you Roberto, best wishes to your parents!
