This is a nostalgic and strangely laid out hotel. The beds were good and the breakfast was quite good. The gal at the front desk was very accommodating and nice Our biggest complaints and cause for the ratings is the window wells with the stairs and table. Strange! It make is difficult to close the blinds at night. We had two rooms and one had a window a/c installed and made it more difficult. The jacuzzi tub/shower combo makes it difficult for seniors or disabled people to get in and out of. It is also quite slippery and could use grab bars in useable positions. Then the parking lot is very strange. Not very convenient for large trucks.

The cabin was "quaint" but was by no means comfortable. The only options for seating are the beds, or the hard dining chairs. There are no easy chair(s) to sit down and just relax and unwind, read a book, or watch TV. The beds are memory foam mattresses, which means that they adapt to the environment they are in, so for an area that typically experiences 5-6 months of winter and generally cooler summers, that means that the memory foam will harden. The result? A very, VERY firm mattress. The $35/night for my dog was, in my humble opinion, not justified. There was literally nothing he could have damaged in the room - no carpet, no rug, no chair cushions, nothing. Also, it is worth noting that I reserved (and prepaid) for a pet-friendly room - but when I arrived, there was no pet-friendly room available and so the check in clerk had to get approval to put us into one of their non-pet-friendly rooms. So what is the difference besides the price (pet friendly is higher)? If there was some feature or amenity, neither I nor my dog could tell you want it was. In short, calling it pet friendly would be a stretch - perhaps consider looking at other options if you are traveling with a pet.
