HARD BEDS, not firm. HARD.
The mattresses are 6-7 inches of incompressible material, on top of solid wood.
I stayed 3 nights, in town on business. I did not get one night of good sleep. After the first night, I texted the unseen staff asking if they had any softer mattresses. They did not, and suggested that I pile up blankets to make it softer. (Yes, that's just the way I like to sleep on an August night. ) I resorted to Advil PM, which made me groggy the following day and made work and driving home difficult.
The location is nice, the room very clean and quiet, but I still would have left after the first night, if I could have afforded to.
