I stayed here for a week while in Boston for a new job. It's a very small room but it was really nice! The bed was really comfortable, clean private bathroom, microwave and mini-fridge, and well-stocked with some kitchen utensils and dishes, snacks/coffee/tea.
Regina was really responsive and friendly. I was able to check in early and store my bag after check out before my evening flight home.
The house is less than 5 minutes walk to the Alewife red line T stop, 10-15 min walk to Trader Joes, CVS, and a bunch of other stores at the Fresh Pond Mall. Really great location to get anywhere in Cambridge.
