This place is quite central to things a tourist would do in Tokyo. Though I stayed due to an early flight as no hotel will accept me this early. Expect most hotels do possibly accept you around 2, but most do it by 3. This place can be checked in as early or late as you want. You get what you paid for. It's good value if you're a full party as it can sleep up to 5 I think. Though basic, early check in was a life safer as I wouldn't know what esle you can do with hours when you're dead tired. After arriving from a long flight, the last thing I want to do is wait around to sleep, or use the bathroom (shower). The only downside is that the building is a little old as the door is hard to open.
As soon as you arrive, the door is already open waiting for you to use the room itself. Good value and gets the job done.
