The communication with Cristina and Isabella before and during our stay was very easy and prompt. They recommended some nice things to do and places for dinner/drinks etc. The apartment is very nice - furniture, bed, kitchen... was new and modern. The area is also quite nice - supermarket, metro, some nice spots to go out for dinner etc is all nearby. But this also means that it's kind of noisy even in the night with all the traffic in this small side street, but I guess this is something you will face everywhere else in Catania as well as the traffic is crazy :) So it was very thoughtful that Cristina provided some earplugs. The air conditioner was working just fine.
Overall we would totally recommend Cristina's apartment.
