This is a great place to stay in Palermo! It's quite spacious and has a lovely south facing balcony. The kitchen is well equipped and great for cooking! The only thing we felt was missing was a proper big cutting knife. Be prepared to wear ear plugs at night, because the streets ant the doves on the ceiling can be quite noisy. But with ear plugs we slept very well!
As for the location, it's great that it's both close to the main station and close to the city centre. But do note that for a solo female traveler it might not be the best choice.
