I had very fantastic two days with Ivana and Cristina in Catania! They are super helpful and kind-hearted hosts, who sent me handbook (electronic version) of places to visit and food to eat in Catania, also introduced the brilliant Mount Etna travel guide. We had a wonderful night by the seashore with local food, which made me feel relaxed as if I was at home. Additionally, they offered to pick me up at the bus stop on the first day when I couldn't find the way, which was very warm.
As for the accommodation, tidy rooms with a set of amenities make it cosy to live in. The house is kind of far from Catania city centre, but the great view of the sea from the balcony can compensate it. Also it is very quiet during the night, suitable for a deep sleep.
The only things to be noticed are the height of the room because it is under the roof, and the stairs connecting to the first floor are a bit narrow, but they not affect my overall review on the stay.
They indeed leave a fairly good impression on me!
