We had a lovely stay and absolutely recommend this apartment to anyone who plans to stay for a couple of days.
The apartment is situated in the middle of the city centre and the perfect starting point to get to know Palermo since everything is reachable by foot. This can get noisy on the weekend but Paolo happily offered us earplugs in case we couldn't sleep :)
While we recommend to eat at lots of places in the city because there is so much to discover, it is also possible to use the very well equipped kitchen (even with some coffee and tea available at arrival).
Extra credits go out to Paolo & Valentino for their detailed and thought through communication. Before our arrival they gave us tips about the transfer from the airport to the apartment. If there are any questions, they gladly answer them by phone or even in person (they live in the same building).
