The Amalfi is fantastic. We stayed in Massa Lubrense, it’s small and quiet. Take the ferry ride, I think it leaves from Sorrento. Positano is a favorite visit. South of the Amalfi about an hour is Paestum, Paestum - Wikipedia

Amazing Greek ruins you can wander right through. A cool little museum also. Makes a nice day trip from Amalfi after the first few days.
It is absolutely beautiful. We are watching the Napels walkthrough right now.
