The apartment is located very close to the beach, but also to the little piazza of Mondello, (with shops, restaurants, cashpoint, tourist information,) and to the fast bus into Palermo city centre (806, round the corner.) Other buses stop right outside the flat throughout the day and there is low level traffic noise, as you would expect in the town location. The metal security shutters block out most sound and all light if you close them completely at night.
The small outside area catches the morning sun and is pleasant to sit in, but is shaded later in the afternoon. (The carpark over the wall from this was empty during our stay, but I expect would be busier later in the season.)
The flat was very clean and the double bed very comfortable. We slept really well. Very hot water for good shower, (although this could run cold if you stayed in too long) and plenty of towels provided. Salvino kindly brought us 2 extra beach towels to use on the sand and allowed us to take fold up garden chairs to the beach. There were also some 'basics' for cooking, (olive oil, vinegar, seasoning, tea, coffee, sugar, ) as mentioned in the listing.
I would recommend Salvino's place to anyone who wants proximity to the sea and services, but with easy transport to historic Palermo centre too. Salvino communicated with me via text from the time I made the booking, was there to show us the flat when we arrived and gave us a lift into town centre to catch the airport bus when we left.
