This place was ideal! We stayed for 2 weeks and had everything we needed. S. Flavia Station is simple to get to from Palermo Centrale, and the apartment is a 20 minute walk from the station. Although Umberto picked us up on arrival and kindly dropped us off the morning we left which was really helpful.
The pool is amazing, it's a gated complex so very quiet and everyone else staying in the complex was nice and respectful. There's a free washing machine which we used twice.
The apartment had everything we needed and was spacious & comfortable.
There's some nice bars and restaurants in town and a nice beach/cove in S. Elia, about 10-15 minute walk (with 2 big hills).
Would absolutely recommend this place, we felt safe & comfortable.
