VERY pet friendly!
My wife, whose sense of smell is quite unbelievable, said that the room smelled fine as long as the air conditioning was on, but smelled a little like urine when not. I did not notice any problem, and I doubt you will, either.
This is no luxury property, but I thought the beds were comfortable, rooms and public areas were clean and, despite being right next to the highway, the interiors are quiet. (Outside is a different matter, and our dogs were just a little spooked by all the traffic noise.)
There is ample grassy area for the pups to take care of their business. All in all a comfortable stay.
