The hotel Frederico II has a lot of positives. It's right in the hotel district, behind the more famous large hotels in Palermo. As other reviewers noted, it's located in a side street, which reduces traffic noise considerably. The hotel looks like it was recently renovated, and my room was gorgeous. The staff were all very friendly, and the breakfast/restaurant were stylish and pleasant. You an walk to the station in about 20 minutes, and visit all the main tourist attractions on foot. However, there were some noise issues - I just don't expect bouts of loud bangs and scrapings between 11 and 12 at night. I have to report that the noises subsided in the wee hours, though they resumed fairly early in the morning. I couldn't figure out the exact cause - maybe a problem with an elevator, or staff doing some work? I hope the hotel can address these issues, because this would be an excellent choice otherwise.
