I don't mean to be annoyingly technical, but Sorrento is the last town before you turn the corner onto the actual Amalfi Coast. Sorrento is on the Gulf of Naples. It's the "last" town you can get to by train, before Salerno, at the other end of the Amalfi Coast. it's a popular destination. I thought a premium room at the Ambasciatori was magical, but few posters on this board are willing to pay the price. And there can be seagull poop if you have a (premium) balcony! Ambasciatori is in a group of five luxury, large hotels. Most posters here stay in smaller places. But the big hotels are right on the cliff, and have elevators to private swimming platforms (boardwalks, NOT beaches) on the Gulf.
We were the last week in may. It was very hot in the daytim, but pleasant at night, and there were too many people waiting for the bus to Positano to fit onto the next half-hourly public (SITA) bus. Enough said?
