Small hotel in the heart of old town. Building is probably XVIII century, renovated of course. Small lobby has tour guides for your use; real guides, not an advertisement variety. A small library of books in multiple languages for reading.
Rooms are not big but excellent: clean, modern look, comfortable mattresses. Kitchen is a perfect example of Italian design and fits inside big cupboard. Daily cleaning. Excellent Wi-Fi.
The only possible trouble for some people could be that a car cannot come to the door - street is too narrow. You would have to carry your luggage about 200 feet. If you drive to Sorrento, the nearest parking is about 5 minutes away.
I have to say separately about receptionists: exceptionally good and go beyond their duties to help. One evening we came about 9:30pm and Rafaella (her shift ends at 6pm or maybe 7pm) was waiting for us to warn about tomorrow's strike on the railroad. She is very nice and always available online.
If we come to Sorrento again, I would definitely stay there and not even look elsewhere.
