We stayed at Angelos place for three nights during our trip around Sicily and we can definitely recommend him.
The flat is located in the heart of Naros old town, directly at the stairs to the duomo and just a five minute walk from the castello. There is a parking space directly in front of the house, but don't always trust your GPS to guide you there. I'd recommend coming from below through Via Umberto I.
In the spacious appartement with seperate kitchen and living room you'll find everything you need. Everywhere was clean, the wifi worked flawlessly and there are even TVs in every room.
But the biggest upside of all was the hospitality of Angelo and his familiy. They have been warm and welcoming and were alwys quick to answer all our questions throughout our stay. One couldn't imagine a better host.
Overall a great appartment with a wonderful host family, can recommend!
