We have stayed at Ruby's twice. We love it. Some rooms are "backpacker" style but there are 4 that have beach front views. Two up and two down. Basic would be a better description. ;-)
You are quite correct, "basic" would be a much better description. On my last visit, I stayed in one of the rooms facing the ocean. It was quite nice. Only one drawback with that particular room (#12)...it was at the top of the stairs on the 3rd floor, so it was as bit noisy when folks were coming and going. My sleep patterns were a bit disrupted, but the view I had each morning made up for it. Will stay there again, I am certain.
