RECOMMENDED but just: This my 2nd visit to this property. To set the stage, you nearly anticipate to see James Bond as you turn the next corner. The setting of this property is from the 60's and like the Queen Mary, the Okura plys the waters in a regal and stately manner.
The hotel is located near to 3 metro stops, but sadly there is scant little in the neighborhood to do/eat, it's pretty dead at night. I don't think I'd recommend this for a tourist visit for this reason alone.
If you have business in the neighborhood, then this is a fine choice. The Okura caters to the numerous nearby embassies and the crowd is mostly older and nearly everyone is in a business suit (so not a hip trendy sort of place). Even when running at full capacity, the hotel is nearly dead quiet.
Having said that, the rooms are comfortable though everything is slowly aging (gracefully). Service is over the top and they run around eager to cater to whatever desire you may have. Cheap though, it is not.
If I have a negative, the American breakfast buffet is not befitting the hotel. Something is missing though I struggled to identify exactly what. My group complained mostly about how the eggs were cooked. The hotel recently added Wi-fi and it's free throughout the hotel (a nice addition).
The short is -- if you're placed here have nothing to fear, the staff and hotel will take good care of you.
