We had a great three nights here. The weather perked up on day two which meant we had lovely mornings on the terrace ( sun goes around 4.30 pm at this time of year and the mosquitoes come out in vengeance !).
The apartment is very near good restaurants and grocery shop and Guido provided bikes for us to use. This meant 5 mins later you were on the beach but otherwise a 15 min walk.
Da Pietra seafood restaurant in Mondello square is charming and delicious.
The beach did have a lot of fenced off (literally fences) private areas which we did not like but there are a few public (crowded though) spaces. Drinks cheap on beach but there was a consistent sulphurous odour no matter which part you were on!
