We just stayed at Buca di Bacco and it was a memorable experience. The location is the best in all of Positano--right on the beach. The room was fantastic--a beautiful view of the ocean, large balcony, an incredible shower with its own ocean view, and the room was spotless being serviced twice a day. The only ding is that there was a lipstick stain on a glass in the bathroom--We were more than willing to chalk it up to something that didn't come off in the dish washer. We also took a cooking class, which I would recomend to anyone--informative and a lot of fun--we also ate the mounds of food at the end in what was one of our favorite dinners. The restaurant itself is very, very good--the lamb chops and fried appetizer sampler were both great. Finally the service was six stars--the staff was extremely helpful and knowledgable about the area and knew our unquie preferences breakfast by the second day. Not cheap, but I would definitely return and recomend to anyone looking for a wonderful stay in Positano!
