Pia was an awesome host, although we never met in person. She was very accommodating with a special request I had and even when it didn't quite go according to plan she was very helpful and understanding. The apartment is in a great location-- a short walk from tons of Palermo goodies. I used the garden one day to read, but didn't make it up the pool. The place is modern and clean, perfect for one or two people.
One small note to travelers: if you are a very light sleeper or want to sleep late and undisturbed, this might be an issue. In general it's very quite back there, but it is on the ground floor, the hallway is very echoey and you can really hear everything, including people using the common outdoor space behind the building. Most of the time not an issue, though.
