We had a lovely stay at Marianna's place. It's right in the city centre with a view on a pittoresque piazza with a church. Lovely to just hang out the window and see the people go by! The appartment is small, but had all the necessary equipment, and a comfy bed.
If you want to stay here with 2 people for a longer period of time, it might be a bit too small, but for a few days during your holiday it's perfect. The only downside was that there is a bar next to the appartment where the music was very loud on Thursday and Saturday until approximately 1 am. This makes sense since you're right in the city centre, but may be something to consider if you're looking for more peace and quiet.

Marianna was a lovely host who was very responsive and gave us clear instructions about the collection of the key, parking, etc. She also gave us a bunch of tips regarding visiting the Etna, parking near the city, and tips for restaurants to try out. All in all, we had a great time and would definitely recommend.
