In one word - splendid!
Nicola is an amazing host! Very responsive to messages, he was all time ready to help us and give us support, very polite and friendly! Even though we had our trip planned with excursions, he gave us suggestions what to see, where to go and where to eat.
Apartment is perfect for two, very close to the main city sights.
10-15min from the main bus and railway station by foot, fish market, fresh fruits market and the port. Well communicated with the airport.
Very clean and has everything you need for a short stay (7days in my case).
Would book again for sure, and would recommend Nicola and this place to everyone who plans to visit Catania!
