We had a great stay during our time in Catania. The host was accommodating and overall things went smoothly.
The AC was really appreciated during the hot days we were staying Catania in for.
What we didn't know is that the place was shared, which while possibly due to insufficient research into the property on our part, I believe could have been better advertised. It didn't take away much, we only really stumbled into others on occasion and were never really in each other's way, but it sadly meant that using the kitchen was off limits to us.
The walls are also presumably quite thick, which can be a plus, but sadly also means that the WI-FI signal has a hard time spreading throughout. In the common room however, where the router is located, the bandwidth is more than adequate.
