Giovanni's place was great. The location was amazing- Piazza Duomo & Via Etnea are about a 10 minute walk away. The Roman theatre is literally around the corner (there is also a really good pizza place 30 seconds away from the flat!)
The flat itself was clean, spacious and comfortable. The little snacks provided were very thoughtful too!
Would definitely recommend this place to anyone visiting Catania.
(Also, the airport pick-up service on offer is very handy and would recommend that too- made our journey much easier and for a really decent price!)
