We were staying in Marcello's apartment with our 1 year old daughter for a month. The place is really good value for the price. Maybe the best about the apartment is the location: far enough from the sea to be quite but close enough to be there in 5 minutes on foot. Bus stop is very close, and if you have a car then there is a free safe parking within the property and the highway entrance is 1km away.
The apartment is big enough for a small family, the view on the Etna from the terrace is really great. Most of the necessities for longer stays are provided.
Marcello is really helpful host, he is answering quickly and provided requested information even before and during our stay. He also proactively got us a high chair for the baby after we asked if he has one. So all in all, good experience, great value
