Poorly Managed Aging Hotel
I live in DC and when my electricity went out during a storm when it was 100 degrees outside, I decided to spend a night in this hotel. I wasn't looking for anything special, just a clean hotel with good service. I came to find that The Churchill is "clean" in the loosest sense of the word, but there was no good service to be found.
Generally speaking, this is an acceptable hotel. It has a bed and bathroom, which is all one really needs. That said, it is fairly old and certain areas have the "nursing home smell". I'm sure the suite was very nice 20 years ago, but years of use had made everything look worn-out and dated. The carpet was in rough shape as were the armchairs in the suite. One of the blankets on the bed had what appeared to be cigarette burns in it, and one pillow was missing a pillow case. When I tried to make myself a cup of coffee in the morning, I was dismayed to see that the element of the coffeemaker which holds the coffee grounds was missing entirely, rendering the coffeemaker useless. The suite was on the top floor looking out on to Connecticut Avenue and featured floor to ceiling glass doors with a Juliette Balcony which would have been nice if the doors were not BOLTED shut and thus inoperable. This is a hotel which shows its age. Perhaps the most fitting explanation for the lack-luster accommodations can be inferred from a line in their Guest Services Book, which said something to the effect of: "This was once a beautiful hotel with an amazing view of the city until the hotel next door was built and obscured our view of the city." My guess: when someone blocked their view, they stopped caring. 
Check-in was by far the worst experience. When I arrived, I gave the front desk staff my name and reservation number. He moved fairly slowly considering I was the only one there, but I had a room key in hand in about ten minutes. I went to the room only to discover it was a standard room when I had reserved a suite. I went back to the front desk to inform them of the problem. Their first explanation was that I had used a booking website and that the booking website reservation "did not guarantee a specific room type." I asked them why the booking website would offer a choice of room types at different prices and send a confirmation that a specific room type was "guaranteed" if the booking website could not, in fact, guarantee anything. They had no response, and suddenly changed their story to say that I did not book a suite but had merely booked a standard room. I asked them why their story changed so quickly, and showed them a confirmation which stated that a "suite" was "guaranteed." Upon seeing this, they looked at their computer again (this time for real, because the first two times they "checked" using the computer that only makes room key-cards) and conceded that I had in fact reserved a suite. They explained that they had checked me into the hotel under the name of the wrong guest. Really? I had to give a photo ID and credit card upon check-in, both of which showed my name, and they claim that they checked me in under the wrong name? I don't buy that for one second. The whole check-in experience made it quite clear that their first two responses ("no guaranteed room type" and I "did not book a suite"... explanations which are inherently self-contradictory) were simply made-up by the staff member in an effort to make me go away and accept less than what I had paid for. What a poor approach to business in the HOSPITALITY industry.
Check-out was also needlessly time-consuming though not too bad. When I arrived at the front desk and asked to check-out, the woman said that they slipped a bill under my door and all I needed to do was give her the key. I said I didn't receive a bill, and she said she would print it for me. Rather than going to a computer and pressing "print," she proceeded to take four separate phone calls consuming a total of 10 minutes. She then printed the bill, took my key, and I was on my way. Two management problems here: (1) I didn't get a bill under my door when, apparently, I was supposed to; and (2) a hotel should be staffed so that there are enough people to both answer phones and deal with one person at the front desk. 
In sum, this is an old hotel that would be perfectly fine if it was managed by a decent staff. Unfortunately, the staff make this a poor choice in a neighborhood with dozens of other places to stay.
