Fantastic view!
As other guests have stated, what really makes this apartment stand out is the view. It is impossible to describe the panoramic surroundings- you really have to see them in person. I am someone who loves to sleep in, but I knew the view of the sunrise from the apartment would be stupendous, and it was. It was definitely worth it to get up early to watch the sun rise on our first morning- you can even see the reflection of the sun on the water in the distance as it rises. The view is so terrific that, if Palermo didn't have so much to see, it would be tempting to stay on the deck of the apartment the whole time.
The apartment itself is very clean, and quite spacious. The shower works well, and it is nice to have a large refrigerator for drinks and stuff. We appreciated the responsive communication we had with Mabbi and Luigi, and also the delicious pastries that Mabbi left in the fridge for us.
It is also nice that the apartment is accessible by elevator/lift. When I heard there were stairs, I thought they might be a challenge, but they weren't at all- you take the elevator to the top floor of the building and then just have a few steps left to get up to the apartment.
One final note is that you can see the Teatro Massimo from the apartment, in addition to other major Palermo sights. Both my husband and Luigi mentioned that Godfather III, which was partly filmed there, was the worst Godfather, but it is still cool that you can see it from the apartment. It is maybe a 10-minute walk from the apartment, which is pretty centrally located, and I'd recommend taking a guided tour there, like we did.
