beware of "upgrades" - room had NO BED - mattress on FLOOR
I checked in after a very long flight, middle of the night, and was delighted to be offered an "upgrade" to a suite. I was given a key and headed upstairs, exhausted. I opened the door and thought there must be some mistake. The room was essentially unfurnished. I can't even find the restroom. I keep looking, and there is no bed in this room. There is a mattress. On the floor. But no bed. It is past 1am, I have to be out again before 7am, I figure with the kitchy decor in the lobby, maybe all the rooms are like this? It was worse than a college dorm room. Peeling wallpaper, not very clean, smelled stale. With the mattress on the floor I essentially felt like I was sleeping in a crack den.
After my trip I asked my office manager why on earth she had booked me there. She was bewildered and showed my a dozen photos of perfectly nice, average rooms with normal, western beds. Turns out only one room in the whole hotel has this crack-den setup, and I'm sure no one ever wants it, so they foist it off on exhausted business travelers who show up too late to arrange accommodations at another hotel.
Note that if at check-in, the desk clerk had said anything similar to "an upgrade to our 'traditional Japanese suite', which has the mattress on the floor." I would have hastily rescinded his kind offer. I was tired, but not that tired. No one ever mentioned anything suggesting a crack-den-mattress situation. After I got back, my office manager called and complained, but they insisted this is a perk, an upgrade. I'm sure a fully-informed couple on a romantic getaway who don't plan to sleep much might like this suite. But this totally bewildered business traveler DID NOT. They were totally unapologetic and inflexible on the phone. 
They also hide the photos of this crack-den suite from Expedia. They have photos of every other room type. I do not believe this is a coincidence.
