The apartment is compact and very quiet (except when the water pump starts - in the morning -, or when the children start running on the first floor - that happened a lot during our stay, especially in the evening). It's about 25 minutes walk to the city center but you also can get on one of the numerous buses at the main road.
There is a simple kitchen inside, including oven. And a shared courtyard where you can sit outside if you like. The bed is on a small void above the kitchen (watch out for steep stairs at night); great mattress on a wooden floor. There's a dining table and pallets with cushions for relaxing and watching tv.
Leandro was very communicative and helpfull! We got bar/restaurant recommendations and he immediately responds when the WiFi didn't work (it didn't during our stay untill last day, despite attempts by an electrician, but we said we don't care) and when the power went off.
Only thing we didn't like too much was the lease contract wich we'd have to sign wich wasn't announced in the advertisement, and a tourist tax to be paid in cash (outside the platform), because those things aren't in line with the Airbnb terms of service.
I would recommended this one for sure. We had a lovely stay and really liked Trapani and other places nearby (don't forget to visit Erice by cable car).
