The check in to the appartment was really flexible and the host was nice and welcoming. Also the service of private driver to pick us up from the airport was very helpfull.
On first look, everything seemed nice and clean, but under closer inspection it really wasn't so. Kitchen appliances and dishes were quite dirty (other guests should probably wash their dishes properly before they leave so this wouldn't happen). Also we had some problems with little ants.
The balcony is a huge bonus for the appartment with great view to the sea. We were a bit dissapointed to not have the barbecue that is showing in the pictures, but we were allowed to buy our own and bring it there.
The location of the appartment is great though. There are some nice restaurants, solarium beaches, shops and markets nearby and also a private parking hall if you have a car (parking on the street is not recommended). The city center is easy to reach via metro, but the busses in Catania don't really work as intended.
Our stay was overall okay, but we would recommend having car even if it is quite stressful to drive in Sicily :)
