This is an old post but would like to relate my experience. I stayed here very recently and the elevator key is a nuisance. There are only 2 elevators and they are directly across from the front desk (approx. 60 feet away). I met three Sp's during my time there and it was a bit uncomfortable having to go down to the lobby.
On one occasion, the lady managed to get in the elevator with someone else and surprised me at my door....sweet. But on another, during midday I got the call from the driver and met the lady near the elevator just as she was walking in and the security guy did a complete 360 and followed her to the elevator to see me standing there waiting.
Some may find this a little embarassing...I didn't really enjoy it to tell you the truth. So, I won't be staying at the embassy if I plan to meet SP's.
On the other hand, if you are not bothered by this it is a great hotel for entertaining. Large kitchenette, jacuzzi tub, separate bedroom, tasteful decor and new.
