Claudio was a great host, very communicative and quick to respond to questions or issues we had. The location of the flat is also good, very central so easy to walk to all the attractions.
The apartment itself is fine - it's kind of like a half floor between main building stories so is accessed via a very narrow staircase which would be difficult to get larger bags up if you had them and means there are very low ceilings. The basic supplies were provided and the kitchen is sufficient for a few days stay. The room is above an outdoor restaurant terrace which might be a nuisance for light sleepers but did not bother us. There is also a smell in the bathroom of drainage pipes which can be a bit annoying after a few days. There was also a lot of noise from the apartment above which is not the fault of this apartment or the host - luckily it was not at night so did not impact sleep but was quite annoying when we stopped for a rest or break from walking - hoping it was just temporary reason but can't confirm
Overall though was a pleasant and central stay for a few nights in Catania
