Did not have a great experience at this AirBnB. First of all the location was not good - it is not a nice part of Catania. It looks like it is close to the sea but you cannot get to the beach from there, and there are no nice cafes/restaurants/shops nearby - have to walk into the town.
The apartment itself is not terrible but nothing special. It looked much nicer in the photos, and also it is up several flights of stairs with no lift.
We also had a problem with the electricity. It was very cold (March). There was a small heater in the apartment. But the heater tripped the fuse after less than 5 mins (even on lowest setting - 400W). So did the water heater so it was not even possible to have a shower. The fusebox was on the ground level so each time the fuse tripped you had to go down 3 flights of stairs to reset it.
Dario did call an electrician to come and fix the problem the following day, but we were already completely put off from this experience, and so left the apartment after just one night (had booked for 7). I thought that Dario might give us some compensation for our bad experience but he did not offer anything.
