I stayed for 9 nights. Maru was always very responsive and tried to make sure my stay went smoothly throughout.
Check-in was super easy, except the place was extremely dirty, sticky, dusty, and disorganized when I first checked into the apartment. Maru quickly acted on the matter, though, and sent in a complimentary cleaning service the next day. Other than this, I didn’t have any issues. The building is very modern and nice. The rooftop pool & view were probably the best one I’ve been to in Palermo.
In regards to the soccer fields, they are indeed right next to the apartment. I didn’t find them too annoying mostly, but there were a couple of nights when people played until 2am, unlike what other reviewers wrote saying 11:30pm.
