Found Hotel is conveniently located near the Boston Common. Taking the T from there is fairly convenient as well. Most of the stations are within 7 - 10 minutes walk. Newberry Street is also with walking distance, so there's plenty of boutiques to shop in and restaurants to dine in.
The single bed room I stayed in was all I needed. It was pretty tiny, but it also has all the necessities.. if you don't need a fridge or a microwave or a table to use for small meals. Within two blocks proximity, there are plenty of eateries, so not having a table or desk to eat at isn't a big deal.
As a solo traveler that is staying only for a few nights, I would certainly stay here again.
