I stayed with other three friends at Oxana and Pierluca's place, and our stay was perfect! The house is very spacious, located in a very nice area of town (near the fish market, in front of ursino castle, near the cathedral). The apartment is very nicely decorated, especially the floor is made of very beautiful tiles. Pierluca welcomed us with every sort of local tip: he recommended what to do and where to eat (we checked: it's all very good!) The house is quiet despite being in a lively neighborhood, and has AC, so we slept well. I would definitely recommend the place... and I had forgotten how beautiful Catania is: I would certainly want to go back!
