Location is great, very convenient for all Palermo's restaurants and close to public transport. The building is also very good, with a large area with sofas and tables on the ground floor (although no wi-fi) and the seating, gym and a small swimming pool on the top floor.
Fernanda was easy to reach.
The flat is pretty basic, but good for a short stay. It's on a second floor, facing a busy street. On a longer stay you'll notice that is missing some things such as a place to hang your clothes to dry or some cooking essentials. Not even bin liners were provided, so expect to bring your own. The building has 2 large washing machines and 2 dryers. However, coins need to be purchased 4 blocks away from the building at a certain supermarket.
I was charged to arrive a few hours earlier and was told when I arrived that I couldn't get in until normal check-in time. Luckily, the misunderstanding was resolved after a few phone calls.
Apart from a couple of hiccups that were quickly resolved, my stay was pretty good and would recommend this place.
