Giuseppe is a great host and very service-minded. The apartment is clean, nice and practical with two bedrooms each with a small balcony. Everything was according to - and mostly beyond - our expectations.
The apartment complex obviously mostly contains locals, and we enjoyed listening to happy children playing outside in the evenings.
If there's one downside, it's that it's a bit away from the sandy beaches of Mondello (although you have very nice rocky beaches very close). We used that as an opportunity to get some good walks every day. If you have a car, that's no problem at all. Plenty of parking opportunities right outside.
I highly recommend the place, both for the place itself, and because Giuseppe is such a trustworthy, solid and service-minded host.
