Paula's place is really great and can easily accommodate 3 people (there were only 2 of us, but there's an extra bed). The apartment is located in a secure property with a 24/7 guard, and the window are facing into the courtyard - so there's minimal noise.
What's more important, the location is hard to beat - you can walk anywhere in Palermo, and even venture further into downtown - everything is very close. There are 2 subway stops within a 10 minute walk (if not less). Separately, I'd like to say that Paula is one of the best communicators/hosts we ever had - she typically responded within minutes, and provided us with lots of useful tips and things to do around town. We will definitely consider staying here again, and tell all my friends about Paula's place also :)
