My girlfriend and I stayed in the apartment for two nights. Concy was a great host. She provided us with some very good tips about our visit to Catania and was very flexible with check-in times.
The apartment was clean and spacious. There was a small amount of noise from a nearby bar on the first night but it didn't prevent us from sleeping.
The best thing about this apartment is the location! It's a short walk to all the main attractions in Catania.
