The location of the apartment was really good, the train station and the bus terminal are really close. Since there is not so much to do in Catania, we decided that travelling around is the way to go.
Mario is a great host, really easy to reach. In fact, the answer came literally immediately every time we asked a question :) Also, we asked for a separate bed for our baby and Mario provided it to us without any problem. We are really grateful for that!
The apartment is ok, it has everything a person needs. It's pretty small, but it has 2 floors with VERY steep stairs. It's a unique feeling sleeping upstairs! The bed was comfortable, but crazy loud and squeeky. I was waking up almost every time I turned, and my husband same. The air purifyer/filter in the bathroom (which is adjecent to the bedroom upstairs) is also very loud. But it turns off as soon as you switch off the light, so it was not a problem.
All in all, I find the apartment pretty good, just something has to be done about the noisy bed. It's difficult to have a restful sleep on it.
