We really enjoyed our 14-day stay. We were received by Susana (early check-in) who was friendly and gave us some very useful information. The apt is an open space with kitchenette, well equipped in appliances (Nespresso machine, 3 ovens) but not much so in terms of utensils (e.g., no frying pan or kitchen knife). The apt was clean, but the sheets, bathroom carpet, and a lot of kitchenware were dirty. It has Netflix, but no TV, and it has AC (a bit noisy).
Susana very quickly had clean sheets and some of the missing things delivered; she told us that they did not expect guests to cook in pans or with oil.
There are mosquitoes in the area/apt, but with the AC on they do not attack. We bought an anti mosquito device that we left in the apt, but its effect was weak.
The apt is in the touristic and safe Palermo, surrounded by several restaurants,bars and nightlife, which can extend into late night. It's very easy to take a cab, which is an excellent (and cheap) means of transportation.
