We have just returned from an escorted holiday. Superior rooms were all taken so no Vesuvius view expected. We had two rooms (428 & 429) on the fourth floor. They had small, well equipped balconies.There was a large terrace next to the rooms with amazing views over the bay.
All the hotel staff were wonderful - a real family team. They would do everything possible to make our stay a happy one. The food was generally typical Italian with a fixed menu, but alternative courses were always offered when we asked. We enjoyed every meal. After a busy day we really appreciated the service rather than having a buffet. Our 40 plus people were served efficiently in rooms with plenty of space. Breakfast was mainly continental - with plenty of options and a token scrambled egg and bacon (which tasted much better than they looked!).
As others have said, the town, location and transport are ideal for visiting the sights. On our free day we revisited Pompeii by train. Crowded, but easy on the train. (Site entrances are free for those over 65.) Trains take 10 minutes to Sorrento, 20 to Pompeii and 30 to near Herculaneum). We would choose this location and hotel again.
