This apartment was a very good value for one person. Since I've been to Palermo a few times, I didn't mind the location too much. It is very close to the downtown. But it is located in a piazza which is a bit rough and rugged, which isn't quite as nice as some other areas I've stayed in. The apartment also had a bit of a damp smell, which was combated with air fresheners. I also kept the door to the backyard garden open most of the days, which helped.
The garden is a real jewel, pretty quite and very secluded from the rest of the block. Overall I would say that for the price, this was a really good value that met my expectations. It would however feel a bit small for two people. Internet was fast, and there were some really nice welcome touches like water in the fridge, and a bottle of red wine on my arrival.
A note about the location: It's really close to a lot for great things to see, so you can walk everywhere. And while the piazza and street look a little sketchy, it was totally without problems, and I felt safe.
