I need to book one for 6 nights and am looking for your suggestions!
Hotel Antiche Mura: very nice place in a good location. Spring for a larger Comfort Room: worth the price for the space. Breakfast is included in the tariff, and the staff was great. Oh, and they have a pool, if you're going during the hot-and-sticky season.
We have booked 5nights at Villa Monica B&B - we learned about them here on the RS forums & then researched it on TripAdvisor - they are the #2 B&B in Sorrento. The price for us is 90Euros a night w/a very nice breakfast, amazing views, true Italian experience - read some of the reviews on TripAdvisor. You don't even need a car - they shuttle you into Sorrento many times a day & can help you set up day trips to surrounding areas- Amalfi, Positano, Ravello, Herculaneum, Pompeii, etc. They have been very helpful already via email.
Probably you have already booked somewhere, but I didn' want to miss the opportunity to add another vote for Villa Monica B&B! ... It's a wonderful place!
Villa Monica B&B! It is ranked #1 out of the B&Bs in Sorrento on Tripadvisor.
heidi,
If you don't mind being a bit out of town, this would be a good choice - http://ilnido.com/
If you don't mind a bit a walk from the hotel into town and slightly more "upscale", you could consider - http://www.latonnarella.com/en/index.php
I you don't mind a bit of a walk and prefer something more on the "budget" end, you could consider (it's right beside La Tonnarella) - http://www.desireehotelsorrento.com/index.php?language=en
