We had a lovely stay at Diego's apartment! It was spacious and beautifully decorated - excellent value for money. Diego provided lots of leaflets for nearby places to visit and gave us his own recommendations on arrival, which we checked out and were not disappointed!
The apartment is in a great location - it's located just far enough out of the centre for our liking but still on one of the main roads so it was really convenient to explore on foot each day. We visited nearby Aci Trezza, Aci Castello, Taormina and Syracusa by bus from Piazza Michelangelo Buonarroti, which is really cheap! We found this more convenient than travelling to the main bus station as the local buses that take you there often don't show up! We found it a nice walk to Piazza Michelangelo Buonarroti.
If you're vegan/veggie, we would highly recommend Plante Lab and Fud in Catania and Moon in Ortigia! We would also recommend Etnaland Acquapark if visiting in the summer - although it's not accessible via public transport and we had to get a taxi (we used Radio Taxis, as recommended by Diego).
We wouldn't hesitate to come and stay again, thanks Diego!
