I stayed in Annamaria's flat with my partner in July 2016. The flat is really nice (recently renovated, well furnished and very clean). There is a big lounge/bedroom with a tv and aircon, a small kitchen with fridge and stove top, bathroom and a lovely courtyard where you can eat meals or chill out.
The flat is located in part of the old city and 5mins walking from the town centre. There are small shops nearby (cafe, panificio, pharmacy and newsagent etc.).
Annamaria was a great host, very attentive and friendly. She even left us some basic food and drinks, fresh towels and toiletries.
Highly recommend visiting Noto and staying here
