The location of this apartment was incredible. I couldn't imagine a better place, in a palazzo next to the Duomo Piazza.
The host gave us a car park in the palazzo, which I would say is essential for anyone with a car, as it would be near impossible to park on the street.
We had a small hiccup at check in as Gwendalina's assistant couldn't find us and we couldn't find her. But after a few phone calls all was well.
You can walk to all of Catania's main attractions from this central location, very easily. The fish market, which offers loads of free entertainment, is in the street behind the palazzo, and everything else is close by. There are also plenty of eating options too.
The apartment itself was beautiful, and had all the amenities you might need. The air conditioning worked well, there was a good sized lift to the apartment. It was reasonably quiet, despite it's central location.
We were taken care of by the wonderful Precy (Gwendalina's assistant) who couldn't have been more helpful.
The apartment does have a bit of a strange set up in that the second bedroom doesn't have a door, and you have to walk through the main bedroom to get to the bathroom. I was travelling with a friend and we often share twin rooms, so this was no issue for us, but you might consider it an issue if you value your privacy.
I notice that a number of people have commented on the hot water. Just to reassure you, we had no problems at all with it.
My only real criticism is that the wifi is very very slow.
Other than that, I couldn't recommend this place more.
