Just returned from an 8 night stay for our family of 5. I agree with the other reviews re the superb views over the Bay of Naples, clean rooms, air con, perfect location, etc. What we liked however was the sense of calm and space. This is partly down to the environment: the hotel sits in some lovely grounds with lots of orange and lemon trees, with a shaded terrace overlooking the Bay - so it was nice, when returning from a hectic days sightseeing, to relax in one of these areas or by the pool (we always got a sun bed, even in the middle of July) and order a drink from one of the waiters. But really its the staff - those friendly waiters (Antonio was great), the managers on Reception, our lovely cleaner, that really made the stay special. I understand that some guests return every year and I can see why.
Try and get a sea view room if you can. Vico is lovely, though we found the restaurants a bit average. Nearby Sorrento had some amazing places to eat, last train back to Vico was 10pm. The bus ride from Sorrento to Amalfi via the coastal road is stunning, and only 3 euros. Finally, note that there is a coach stop outside the hotel taking you directly from/to Naples Airport and even a daily service to Rome.
We can't wait to return.
