We only met Davide at our arrival. He was very punctual an professional about everything. He offered us full privacy but cared if we were all right - he sent us a text asking if we needed anything, which was very nice.
His place is lovely! You have everything you need at your disposal, nice kitchen with stove and utensils, cozy dining table, the upstairs bedroom has a large window and balcony.
The only missing thing was the internet, but if you really want to disconnect from work and relax that might prove to be a good thing.
Very close to Piazza Duomo!
We enjoyed a nearby restaurant called Etna Rosso, on via Etnea, actaully a wine bar - we worked out that they have €10.000 worth of wine bottles on display inside :)
Also make sure you don't miss Castello Ursino!
