Spending some time next week at the Marriot in downtown Boston. Which gyms are the closest and which do you guys prefer? Probably wont have a car so if anything is close that would be awesome...
You can walk to MetroRock - it's around 1.1 miles from the Wellington T Station - but you'll have to cross a super heavily trafficked main road. I have walked it in around 20 minutes. Take your pick.
