My friend and I had an excellent one month stay in this apartment!
Two things that stood out were:
#1. Air Conditioning! I am now staying in another place in Sicily without air condition and it can be quite tough at times. The fact that this place has air con made it very relaxing to spend time in and work in.
#2. Wi-Fi! Lots of places have Wi-Fi that is weak, but this was not the case for this apartment. The connection was super quick which allowed me to remote work without any hassle.
Aside from the apartment, Palermo is a fantastic city to visit in general. The main places to go out are a short walk, and we even extended our stay in the city because we liked it so much. The people are so open compared to the North of Italy and we have made many friends in a short time.
Highly recommend this apartment, its location, cleanliness, wonderful host, everything! :)
