Not really for me
We stayed in this hotel for three nights. It was one of those advertised after booking a flight to Washington and is well-positioned with a view, for some, of the Capitol some 400 yards away. Sadly, although our room was large and comfortable, the view was of an ugly office building across the road. I would not normally stay in such an up-market hotel, but the offer was so reasonable, and the hotel so handy for tourists that I booked it. 
What was immediately apparent, as soon as we arrived, was that the hotel is grossly over-staffed. Indeed, it reminded me of the comedy sketch by Michael Palin, where armies of servants are each assigned a trivial task. Whether one wishes it or not, doors are opened and suitcases grabbed and transported a few yards, after which a tip is required. There were insufficient items in the bathroom, and I had constantly to call room service for replenishments. Presumably, my tips were insufficient, because on the final occasion, my call was ignored. 
While Washington DC is arguably the loveliest capital in the world, we could find nowhere to eat that was quiet, with a decent menu. In my opinion, American food generally ranges from bad to mediocre. But apart from that, I find it difficult to enjoy a meal surrounded by people who are yelling to make themselves heard above the music, if one can call it that. (I foresee much future litigation brought by semi-deaf former restaurant staff!) 
On our first evening, having unsuccessfully sought a quiet venue to eat, we arrived back at the hotel and ate in their restaurant. I have to admit that the food was excellent, though expensive. Additionally, the background music was restful, and not at all intrusive. However, the ubiquitous staff made me smile: one man took us to the table, while another took our wine order, and yet another took our food order. Meanwhile, a fourth man stood in the corner with a water jug, and rushed over to top up my glass each time I took a sip. I found this last service just a trifle irritating. However, the meal and the wine were so good, that I conveyed my satisfaction to the ‘food waiter’. Then came the bill, which was about half as much again as I would normally spend. I left what I thought was a sizeable tip. But the waiter, who until that point had been very friendly, was hardly discreet in checking to see just how much tip I’d actually given. It couldn’t have been enough, as he turned, and went off in a huff!
I always wonder what kind of people would choose to stay in this kind of hotel, certainly not usually those such as I, with a modest income. Apart from its size making it so impersonal, the constant need to tip makes me uncomfortable: I either tip too much or too little. Besides, in Europe we feel that tipping establishes a hierarchy which should no longer exist in an equal society. 
To sum up, we did feel that we had received a good price for the accommodation offered. However, breakfast was not included, though we knew that Americans like to breakfast out. Then again, seeing what was available in the vicinity, we opted to eat at the hotel anyway, and were not disappointed. There is a comprehensive breakfast menu, but I would advise choosing an option where coffee and juice are included. Otherwise, the cost starts to mount up.
