This is a beautiful hotel overlooking the Bay of Naples. I cannot say enough about the view of Vesuvius from the restaurant. It is amazing. The staff were wonderful -- so kind, helpful, and thoughtful. Our garden-view room was lovely and well-appointed. If you are traveling by train, make sure that you have a phone to call the hotel for the shuttle pickup. There is no pay phone in the tiny train station although we saw many pay phones throughout Italy. We had momentary panic when we arrived, but were finally able to flag down a cab with a driver who didn't know where the hotel was -- even when I showed him the address. It turned out to be 2 minutes away, but I had to talk to the driver's English-speaking friend on his phone to make sure that we were headed in the right direction. It was a bit of an adventure, but nothing serious.
We had a wonderful meal at the restaurant on our first night and then went to Sorrento by train on the second night. There are not a lot of restaurant/shopping options in Seiano and we didn't expect that. I definitely recommend this hotel, but you need to understand that the location is before Sorrento. If you want to see Positano and Amalfi, you will need to take the train to Sorrento and then hop on a bus to see those towns. It didn't work out for us because we were only staying 2 nights and chose to see Pompeii and than have dinner in Sorrento, but that's just another reason to go back.
