Me and my best friend Linda stayed one night at Riccardo's place.
He was a great host. Firstly he was very flexible with our arrival time and secondly he is very well organised and professional. In his appartment he has free Wifi and even a printer, so we could print out our boarding passes for the flight the next day. This was perfect!
Moreover he has a room full with information about Catania (trips, restaurants, etc.) and he answers every question.
The breakfast was perfect and more than enough.
The bathroom is big and clean and he has all the stuff you need (hairdryer, washing machine, towels, etc..)
The room is near a big street, so if you are sensitive with noise you should wear earplugs at night.
We feeled very comfortable at Riccardo's place.
