I considered the Tokyo Station Hotel, but it seems it's fully booked up and only the most expensive rooms are available ($1200 a night). I would like to try it in the future though, seems like a cool concept.
I'm at Tokyo Station Hotel often because I like the Toraya cafe within, but it's not anywhere I'd consider staying (and I'd get Hyatt credit, too). The value proposition seems very poor for relatively small rooms in a property with such limited public/guest space
, and AFAIK it's not even accessible from the station directly.
EDIT: As per corrected below.
