My friend and I had a wonderful time in Gaetano's flat in Catania. Location is superb, within walking distance of all the main historic sites. The rooftop terrace is gorgeous and a real treat! We just wish we'd had more time to enjoy it!!!
We lived our Etna trip recommended by Gaetano, with the company called 'Sabbia Lavica non solo escursioni', with our guides Nunzio and Alessia.
A good spot if you want to sunbathe and swim in the sea is Aci Trezza, which you can get to on the local buses.
Gaetano is a great host, he's very helpful and always responds quickly to messages.
I would thoroughly recommend!
