Comfortable place, plenty of blankets and pillows (check in the coffee table for more blankets!). If you're sensitive to noise, note that most of the unit is heated by a wall-unit heater so it can be quite loud having it going all the time. i found that turning it off before bed was good, then turning it on in the morning and as needed throughout the day.
the bathroom is heated by a hot water pipe (it might also just be the upstairs neighbors hot water pipe, unsure, but it works either way :P) so at night when the wall unit is off, i'd keep the bathroom door open to let the radiant heat spill into the bedroom.
the unit is very close to the sedgewick stops on the brown and purple lines and is also very close to the 72 route bus which will get you to the blue line no problem. the host, Sara, is incredibly kind and communicative.
