Bea's place was great -- very close to San Marco and all the buses if you need them. It's about 15 minutes walk from the Duomo and about 20 from the bridges. I like that it's close enough to most of the things first time visitors want to see but it's outside of it enough that it still feels somewhat normal (not too touristy). Bea is very helpful with my questions about places to eat, to find leather goods : ), groceries and laundry. She even offered to walk me to those places if I wanted/needed. She is also very responsive in our communication. Overall, I enjoy my stay at her place and would recommend it to any solo travelers.
