The room was very nice,, modern, proper kingsize bed, with lots of pillows and had a great view of Grovsner Square
We paid about 132 pounds,, but I think I saw that the going rate right now is about 108? The breakfast was a very good buffet as well. Also they have a japanese restaurent called Shogun which was very romantic. If you are facing the square, you can see the Embassy from your window. It's close to the Bond Street underground. If your appointment is that early, I would definately stay there for how close it is. I personally am not a morning person lol. Good luck!
Edit:
Actually Missy, it looks like the room rate varies. You may want to phone to see if they have any 'specials' going on
