I had a wonderful time in Boston where I attended a course/conference and also stayed an extra 2 days to explore the city. Katharine and Scott are wonderful hosts, very pleasant and accommodating. Their place is charming, very comfortable, and is at a very convenient location. It is a very short walk to the Green Street subway station on the orange line, which makes it very easy to access the downtown core. From their place, you can also go downtown by bike as there is a very nice bike trail. Hub bikes are available at the subway station. They were very kind to lend me a bike for a day during the weekend. I would highly recommend their place if you come to Boston.
