It's a perfect place to stay if you want to enjoy Mondello beach. The house is just ten minutes away from it. The bus stop to go to Palermo is at 5 min walk (and it takes around 30 min to reach the city. Make sure not to come back too late though, the last bus to Mondello is around 22:30, and the taxi is pretty expensive). The place itself has everything: kitchen utensils, towels, bedsheets. It's very spacious, there is AC in every room and in the kitchen. The terrace is amazing, very spacious with a splendid view. Everything was very clean when we arrived.
I also appreciated a lot the attitude of the hosts: they tried to make our stay as comfortable as possible. Charlotte helped us out by driving us from Palermo, because we arrived too late and there was no transport. She also gave me advice about what places to see (ask her about the lighthouse!). Wherever we had a problem - she was always there to help. Highly recommend!
