Based on previous reviews we opted for a superior room. It was modern, very spacious and comfortable. Everything is spotlessly clean and there is free wifi. The staff are also very helpful and friendly. Breakfast was fine, nothing special.
The hotel is conveniently located, about a 5 min taxi drive (around EUR20 believe it or not) from the central railway station on a quiet street. There are some good restaurants just around the corner in Piazza Marina. The waterfront is also very close although touristy, not particularly attractive and not necessarily great value for money. Attractions such as the Capella Palatina (a must see, but plan your trip as it closes for a few hours during the middle of the day and there are queues to get in) are around a 25 min walk.
Don't even think about taking a car there. Driving is a particular challenge in Palermo and car parking is at a premium.
