Stayed here two weeks ago and ended up in what must be the smallest room, the king bed barely fit and the shower was literally next to the door when you walk in. There was no partition, let alone a sliding or closing door to the "bathroom." Truly a micro-unit type of situation. For the rate, this place is TINY! Some of the rooms are larger, from what I was told after checking with the front desk (they also had plenty of room and I was NOT upgraded at all. I'm a couple of stays away from Explorist, which i know doesn't mean much, but as Discoverist I'm nearly always upgraded in some way or another at other Hyatt's when occupancy is modest).
Anyway, cool hotel, what I would expect from a Centric in a historic office/commercial space, but man, Tokyo-sized rooms.
