Erice is a lovely medieval village high up above Trapani, and Valleria's house sits on one of the main streets inside. The location means it's just a 2 minute walk to reach the restaurants or main pedestrian-only streets.
As there were no other guests during my 2 night stay, I had the place (including shared bathroom) to myself. Parking is free nearby at least until the Summer months and it's not a 10 minute walk as someone previously suggested, but closer to 5 or even less once you work out the winding streets of Erice. It was great to walk the empty (slightly creepy) streets in the evening when all the day-trip tourists had left and it was just a handful of locals still around.
It can get a little cold in the evenings because of the floor tiles and the wind and Erice being high up on a hill, but there's a heater in the room if you need it.
Valleria is a kind host and recommended a great restaurant that was enjoyable and with a fair price too.
