couple places to check out, not knowing what your budget is. keeping you close near the cruise port in santa croce area with vaporetto stops. europeforvisitors.com has lots of info
ca' san rocco
hotel carlton capri (across train station down at end of alley). we stayed here, it was convenient to the grand canal, train, vaporettos, private water taxis, cafes, people watching (ristorante da nino on grand canal had my favorite tiramisu and prosecco)
albergo marin across carlton capri with outside tables to relax
i like to use booking.com and searching all about the places. read fine print and pictures, exact location and not having to retrieve key somewhere else, stairs/steps to climb, cancellation rules, size of beds, reviews. send email to ask questions and book direct with hotel. know arrival corresponds with check in, luggage storage. enjoy and have fun.
