We have twice stayed at the Conca Park. Wonderful hotel, and the food was excellent. Immaculately clean and all the staff were very friendly. If you want a sea view you must book it beforehand. The view over to Vesuvius and the Bay of Naples must be one of the great views in Europe.
We went to Capri for the day and went up the chair lift to the top. Bought a Neapolitan ice cream for 3.5 euros and gazed over the parapet to the Amalfi coast, Sorrento, Vesuvius and Naples. I defy anyone to better that for quality and value for money.
