Massimo and Toni are fantastic, friendly hosts and the location is very convenient. The apartment was very clean, and also felt very safe as it has it has a locked door on the first floor with security cameras, and two locked doors to get into the apartment itself.
Lots of buses available in the piazza directly outside:
Airport Bus (~25 minutes)
606 to Mondello Beach (~20 minutes)
101 to downtown (~20 minutes)
107 to the port (~20 minutes)
628P to Isola delle Femine (~50 minutes)
Make sure to eat at the Tre Porcellini (Three Pigs)! Sanlorenzo Mercato--a bit to the north in the Chinese Palace area--is a short bus trip away (several busses) and has great food and a fun atmosphere.
Thanks Massimo and Toni for a fantastic time in Palermo!
