My girlfriend and I stayed at Naussica's apartment in Catania for one month and felt completely at home. It couldn't be in a better location, especially if you enjoy cooking as I do. There is a daily food market directly below the apartment, and in just a short walk there is the famous Catania fish market, which is quite incredible.
There are also plenty of nice wine bars, cafes and trattorias walking distance. Some of our favorites were Cavaliere for inexpensive Sicilian food, Vermut for small bites and great cocktails, and Razmatazz for an aperitivo or a delicious dinner that's different from regular Sicilian fare.
We really enjoyed our time in Catania and exploring Sicily. Naussica was a wonderful host and quick to respond any time we had a question - whether it was to get a suggestion about Catania or fixing something in the apartment. She was even kind enough to take my girlfriend for a haircut.
