Awesome staff!!
My mom stayed there a few weeks ago and was extremely pleased with her stay. It was only to stop in Boston for 1 day during a trip from Montreal to Cape Cod. Location was great, free parking and very close to a subway station. The day of the check-out her car would not work. Even though she had a discounted rate, the employees extended her stay and took charge of everything for the car. 
I believe special thanks are due to Andy who took it upon himself to call AAA and then arrange everything for the car to be fixed.
Great place, even better staff. Definitely a place to stay in Boston!!
