Pet friendly, cold AC in hot hot summer, secure nearby parking for €10/night, decent size flat panel TV with HDMI access, effectively darkening full coverage exterior window/door shutters, and last but not least, a really great location for walking to sightsee, this place has everything we needed for a 4 night stay in Palermo. For those traveling with a dog who prefers grass for 'business', there are a few patches within a short distance, very close to the parking garage (one of the easiest we've used in Italy so far).
As has been noted by other reviews, be advised that there are 50+ stairs to get from ground level to this apartment.
