Definitely as advertised. A simple bedroom and shared bathroom. No frills, and nothing fancy.
Pros: Great price, warm bed, working shower, location less than 15 mins driving from downtown, Neighborhood quiet and diverse. Coffee maker, fridge, and microwave in room.
Cons: shower had some trouble draining, some little things were missed (eg there weren’t any cups in the room for the coffee), and walls are thin, so you can hear other rooms.
Overall it was a great value and we enjoyed our stay in Boston.
