=The bedside lamp didn’t work. They had to replace it. =The room’s telephone didn’t work t all. =In the walk in shower, they had liquid body wash but they didn’t provide a face cloths to use it. =The regular overhead showerhead worked, but the handheld shower appliance didn’t. =Television had Google TV with no LOCAL channels at all. There was no local programming; NO current NBC, PBS, ABC, CBS; no regular programming/local weather/late night shows. =That said, the room was very clean. They offered free parking which, in the Boston area hotels typically could range from $35-$60 per night.. Take your chances with this one

Spotless and very clean. The service was fast and warm. Parking very accessible. The only ick is that they sell none. If you want water or a can of soda you have to go to a different place or drink from the sink🙁
