Anna's place truly is in the heart of Catania and thus a perfect place to stay if you intend to explore the city by foot. The historic sights as well as the harbour are a stone's throw away and the bus stop for the airport shuttle is also right around the corner.
The place itself is equipped with everything one needs and even has a cute little balcony. Everything is compact but very efficient.
(I would advise for light sleepers to take earplugs along, since the outside walls are rather thin, however that is obviously not Anna's fault - just a heads up from a fellow light sleeper.)
