We had 2 extremely comfortable nights here. The room had a king bed with a Tempur (special foam) mattress. My husband and I are very different weights/heights and I have spinal arthritis yet we both slept well. The bathroom was huge with a separate bath and large shower and many amenities - also good lighting.
The hotel is close to Shimbashi Station. (But if you have a lot of luggage you're best to take a taxi to/from the hotel.) There are many cafes and restaurants in and around the station if you want somewhere close by.
