Worth every penny. My wife and I stayed here during our honeymoon and it was our favorite spot. The location is great, the service is excellent, and the views are unbeatable. They have activities included in the (admittedly very high) room rates that we took advantage of: Italian wine tasting, daily two hour boat rides to Amalfi, a hike to Nocelle. The rooms were a great size - we had a private balcony with ours - and the linen sheets were an interesting, special touch.
All around great stay, very romantic, and one of our favorites.
