Positano, though picturesque and quaint can turn out to be a bit of a crowded affair for visitors who wish to stay over.
Barring price, the Palazzo Murat is your ultimate solution. Secluded, yet 300 yards from the beach and in the midst of the town . Great breakfast catering to all tastes, comfortable and spotless rooms (opt for the old section seeing you have decided to " take the "financial plunge") welcoming, attentive and responsive staff.
A beautiful garden where drinks and breakfast may be enjoyed away from the bustle.
Ask for hotel recommendations re good ( family owned) local eateries. Settling for expensive hotel restaurant (albeit Michelin star) is not a must.
