My partner and I stayed here for 5 nights in late March 2016 and we had a great time. The apartment has a great location. The gym in the floor 31 (I believe) is great and has a stunning view, even if you don't feel like working out, just go for the view (day and night). Eyenit (Yamila's mom) is awesome! She'd go out of her way to help you. The 24/7 security in the building is a plus.
Walking distance to the main area of Palermo Soho with lots of restaurants and bars. 3 blocks away from the Subway (Plaza Italia).
