The location is great, it is less than a minutes walk from the main street, but it is located at the back of a courtyard behind doors, so you don't get any of the late night noise that you would expect from such a central location.
The accommodation is very nice. Big bedroom with plenty of storage and a comfortable bed. There is a large kitchen lounge and a nice bathroom.
The pictures are a proper representation.
There is no parking outside, but the host directed us to free parking about a 5 minute walk away.
We did have to wait awhile for the host to arrive, but maybe this was because we arrived at 6 on a Saturday evening. When they arrived they were very friendly and helpful.
This was our first Airbnb, so we were a bit wary, but we really liked it, and would happily stay there again on our next trip to Trapani. We also loved Trapani.
