Next April will be our third trip to the Amalfi Coast. Actually, on our first two trips--both in March--we didn't technically stay on the A.C. In 2015, we stayed in Salerno and in 2017 Sorrento, which is on the other side of the peninsula.
Need to know the time of year to advise correctly because from May into October the A.C. will be very, very crowded. Don't let that stop you, however. There are ways around it. In those months, you stay in Salerno and take the ferry to the A.C., daily if you want. Salerno doesn't have the hi-top views, but the lungomare walkway along the sea is beautiful, the Old Town is charming and restaurants are fabulous at about 70% of the prices on the A.C.
Another advantage of staying in Salerno is that, in 6 days, you'll want to do other things. Paestum--40 minutes south on the train. Naples--50 minutes north on the train. Pompei--train to Naples, then walk downstairs and take the Circumvesuviana train--it reminds me of a city subway--not dangerous but weird characters--40 minutes to the Pompei entrance.
In April for us, only for 3 nights on a 16-day tour of Florence, Rome, A.C,. Taormina (Sicily) by train, we're basing in Salerno at an inexpensive but personally-recommended hotel directly across the circle from the Salerno train/bus station, Hotel Plaza.
