The room was very good size and had plenty of room, much larger than most I've been to. Its a bit run down but has its own charm kind of a throw back feeling, It was very close to almost everything in the white mountains area.

The property was clean and staff was friendly. Location is in a safe and vibrant part of town. Very walkable area. but the breakfast offerings were inedible for anyone with a gluten allergy. Literally every choice was gluten with absolutely no fresh fruit offered. It was all waffles, toast, muffins, cereal.
