Recommended hotel in Sienna?

I second the Bernini! It's been years since I was there but they're consistently getting rave reviews from travelers. The views from the rooms/ terrace are amazing, it's inexpensive, and in a good location inside the city. A number of hotels in Siena are located outside the old city walls, which is fine if you have a car but not that convenient if you don't plan to drive. Within the city walls, there are also many B&Bs to choose from - many are reviewed in Tripadvisor.
