The flat is really nice and finished to a high standard, the pool was really quiet with only me and my friend using it most days. Getting into central is relatively easy as there's a tram stop less than 5 mins walk away. Getting to mondello beach does take some time tho as it's pretty far away, up to 1.5hours some days. The hosts were very welcoming, and had filled the fridge with some small items on our arrival. My only negative point is that it is next to a main road with a hospital next door so it can be noisy with the balcony doors open. At night tho the double glazed doors keep most of the noise out.
Highly recommended.
