I really enjoyed my stay. The location is really excellent as you're in the just outside centre of the city. Shops and restaurants are within walking distance. Some of which are superb, better than inside the centre.
I stayed to work remotely for a week and the flat was really good with all the amenities listed so it was easy to cook my own meals. It can be a bit dark in the living room though as the lighting is provided by a single row of spotlights in the center of the room. Wifi is provided by fibre optic and is blisteringly fast: around 200Mbps download speeds and 150Mbps upload.
Salvo (who manages the property) communicated with me really well and was friendly and informative. He helped answer all my questions really quickly. I also arranged a tour to visit Etna which was a seamless process, very good value for money and flexible with dates.
I'd be happy to stay again!
