Devora's Fort Hill apartment is on the top floor of an older building that has been divided into a few different apartments (3, maybe 4?). The renovation is recent construction and was very very well done, we were really impressed by the quality of the space and its thoughtfulness.
Checkin was easy -- Randy lives onsite and met us on the official host's behalf. The plot immediately adjoins Fort Hill Park, which was also a nice hang on summer evenings.
The property is probably best visited by car, though there are some local destinations one could walk to, or you could get the T down on Columbus relatively quickly. (Only downside here is you're sort of halfway between stations rather than there being one right there.)
We would absolutely stay here again, and plan to check on availability on _any_ future Boston trip first thing. Legit 5 stars, no hesitation.
