I had a great stay. Palermo is a beautiful city, and this room is right in the heart of it!
The apartment is up four flights of steps-when you first enter the building it feels really old and worn, but the apartment itself is really modern and clean. There are several rooms that Frederica rents out, but I didn't see too much of the other people and I didn't have trouble with waiting for the bathroom (which was very clean). The view was amazing and the room had a desk and wardrobe and felt really homey. The bed was definitely large enough for two, and the kitchen was nice (though I didn't cook).
Frederica was extremely helpful and sent me details of lots of events that were going on in the city. Her boyfriend Alessandro met me halfway to the apartment and gave me a map detailing where I should go and see. He even rescued me when I was too silly to figure out the door and was locked in the apartment!
Frederica helped me understand how to get to the beach at Mondello (highly recommend- its very close and easy to get to once you understand the bus system) and there were a lot of restaurant recommendations hanging in the kitchen.
Overall, I had an amazing stay and I was sad to leave this apartment and Palermo!
