This ship has sailed. Don't. Stay. Here.
We were given three nights stay here as part of our honeymoon present, so I feel bad to sound ungrateful. But, people need to know that this place needs to be given a miss!! 
Bellhops are very clearly working for an expected tip....they always ask you if you need their help, rather than just be helpful. This to me means an unspoken question of, "I'll help, but you'll need to pay, sir!"
 The staff at the registration desk were very cold and seemed to have an attitude. Not nice at all at check-in here, when you expected old school hospitality. 
The room itself was a disaster; I'm sorry. Our first room didn't have hot water. Yes, you are reading correctly; at this supposedly swanky hotel we were checked into a room with no hot water. After speaking to the manager, he admitted that they knew this room had problems but thought it would be ok. Really? Why not check it before putting guests in this room. So after our first night without hot water we were put in a second floor suite (to apologize for the disaster room, we got 'upgraded' to a suite....). This suite as I mentioned on the second floor, had the view of....well, a/c units. If I had paid for a suite and was given this, I would have made a huge stink. So,obviously we were given the suite they can't sell. I was tired dealing with the manager...so we shut up and stayed out of the hotel mostly. A pity....
We were also given club access as part of our 'apology'... One sound....: eeeew! We were there once, for 10 minutes. This is a luxury hotel????? 
The room itself had very low light, so even with all the lights on (oddly placed) within the room, it was still poor light. The toilet runs...every 4 minutes the bowels refills. Super irritating. 
We ordered two wine glasses and a wine bottle for a bottle of wine we bought; we had to phone twice for the glasses to come; then the waitress informed us that they have no wine openers. What a lie!!! The night before, our family had wine and room service delivered for us and that bottle of wine they bought got delivered with a wine opener! 
The Wi-fi came at a charge. I don't understand how people can still charge for Wi-fi when it's so common, and inexpensive overall. Should be complimentary, especially at a luxury hotel.
We did love the Aveda bathroom products...
I guess that brings me to the next thought which is that this hotel is for old, stuffy people or Euro trash. It doesn't claim to be trendy or fun, and it isn't. Its stuffy or semi-functional because of where it lies geographically. It does claim to evoke a sense of history and timeless grandeur. If you like that great, there is a place in everyone's life for all that. Not for us though. I was aging x2 every day I stayed in the hotel.
The Cafe Promenade served delicious food, for the price it is expected. We had a 100$ voucher to spend there, so we were kinda forced to eat there. Service again, was stuffy and not very friendly. 
The only great thing is, the situation. It's close to the underground. It's close to all the sites. 
Overall, we would look at staying elsewhere on my next visit. There surely has to be a better experience that combines luxury with a little fun, and life in DC.
