We had a fantastic time staying at Villa Celentano in Positano - the only downside was that we were only there for 2 days!
The reception was wonderful, incredibly friendly and helpful. The room was large, with all conveniences, as was the bathroom. The private balcony was again the size of a big room, with sunbeds, a table and chairs, where you can bring your own food - "the restaurant with the best view in town". They're not wrong!
You can walk down to the beach or into town, and the walk back up is lovely, especially if you stay off the road with cars but stick to the little streets. You'll build up an appetite going up, and luckily the hotel is surrounded by other hotels and restaurants, so there's no lack of choice.
We arrived by Sita bus from Amalfi, and left by ferry, via Capri, to Naples. We much preferred the second option, which is a more expensive - but much more pleasant way of travelling (with cases). Both are easy to do from this hotel.
