We had a great time at Cristina's!
She and Rob are such great hosts: they are very friendly and gave us good advices for our trip in Catania and after.
The B&B is really well located close to the Castle. Walking around Catania is easy from there. We had no problem for parking (with a car not too fancy) in the street. But there is a public parking available if needed (10€/ night).
The room was nice, comfortable and well decorated.
There are 2 bathrooms available (one big and one small) which can get a bit busy in the morning.
Breakfast is good and healthy and perfect for a big day walking or hiking in mount Etna.
Thanks Rob and Cristina for your kindness and all your advices. We will gladly come back!
