We had a very nice vacation with a group of 6 friends. The apartment is high up so you can look out over the roofs in the city and see the Etna. There is a lot of space throughout the apartment and the communication was very easy. The only criticism would be that there could be a few more cutlery/kitchen utensils, however it is very easy to find a nice, affordable restaurant within walking distance anyways.
All in all a great stay for a family or group of friends for a nice price
