The stay at Paolo's apartment it's a five star stay not because of the flat itself that, in my opinion, could be kept in better condition, but because of Paolo himself who is the most responsive host you could ever imagine!
We never met but it was like having him by your side, full of suggestions, (actually great suggestions) about food, nightlife and surroundings.
The location is perfect, central, a little too central if you travel by car because you will have to pay a little fee for parking the car but Paolo knows how to drive you to the right places. Next to the house you will find whatever you need, nice shops, great bakeries, fisherman, bars, restaurants... well Trapani it's a beautiful city!
And don't be scared of eating too much : you will burn the fat climbing the 4 floors until the apartment (and you can take also a little rest having a chat with the 3rd floor very sicilian neighbours...)!
