9.2/10 Wonderful! (266 reviews)
Ive stayed here before. Rooms are nice because they have a desk kitchen snd couch. Bed was not good. We stayed here because our ac went out. I called and confirmed pet friendly booked and paid for the room only to arrive and be told its $100 pet fee. Thats not fair or ok.
