The rooms were really small. We are fairly light travelers and used to small spaces, but this was quite small. We've stayed in more spacious rooms in Japan, for goodness' sake. The windows were also small and the views were not good (the industrial parts of other nearby hotels). There was also no phone in the room, so they expect you to use your cell phone to call the front desk, which is not so convenient if you're an international traveler and have to pay for minutes. I don't understand how such a sub-par hotel room in an out-of-the-way part of a not-so-glamorous city was this pricey; I know Frankfurt hosts a lot of big conventions, but we weren't there during a convention time, so that wasn't it. I suppose it's close enough to the central train station that you could walk (it's about 15-20 minutes), but it's in a new sort of industrial hotel area that is weird and not that nice, so I was just at a loss as to what we were paying for. It was clean and the staff was friendly, but overall, we were very underwhelmed.
