The flat is ideally located between the train station and the old town (10 min walk from each, from the train station it's only bike lane so ideal for heavy luggages!).
Access to the apartment is made by narrow stairs (3rd floor).
The flat is well equiped and cozy, the shower is great !
Quick note : if you want to cook there is only one hot plate (but it's working really well)
The little balcony is a great + , you can see the Etna when it's not too cloudy!!
Francesco was really quick to answer and accommodating with the hour of our arrival :)
I'd recommend staying there if you plan to spend a few days in Catania !
