To start with, Nicola is a great host! We really enjoyed the 4 days in Catania. His wife greeted us when we arrived and told us if we had any questions we could always write to Nicola and as we did he always immediately responded.
The apartment was exactly how described. Everything was very clean and fine. The apartment is located near the city centre so you can easily walk there.
Would a 100% recommend staying in Nicolas apartment!
