Nicolo answers questions very quickly and is also quite accommodating regarding check-in and check-out time.
The apartment is clean, very spacious and with excellent natural light. It was a special treat to have a good view of Mount Etna covered with snow! The beds and sheets are very comfortable. There is enough storage room for clothes and luggage which helps to keep the place organized. Also enough outlets to use computers and charge phones, etc. We used the kitchen to prepare light meals and found the necessary gadgets to do so. Nicolo was kind enough to leave some usual pantry essentials in the kitchen and even more - many treats!
The location, a few blocks from the train station, is convenient for arrivals and day trips. A second pair of keys would have been helpful since people have different plans on certain days.
Any light sleeper should consider bringing ear plugs as the area is very noisy until late night and also very early in the morning.
