We had three stays here over a seven-week period. Initially we stayed on a Friends and Family rate, but we later switched to a government rate as we got reimbursed for part of the time. And the government rate was the maximum that I would pay for the hotel.
The rooms are nice and always clean, the beds are very comfortable, as usual for a Westin, and the service was friendly. The gym and pool were nice, although I only used the gym. The restaurant was quite good, although oddly the bartender claimed not to be able to make a mixed-juice beverage for me (Hint: pour in one kind of juice, then another.) The location is decent, although a bit further from Old Town than I would prefer. Certainly it is excellent if you have business at USPTO or the Federal courthouse. It was nice to have the free shuttle, although it was indeed a bit erratic in departures, and it stops at 10 pm, I believe. Anyway, the Metro is a short walk away. The location turned out not to be great for our purposes - going up to Arlington - but that's certainly not the Westin's fault. On street parking is free between 5 pm and 8 am weekdays and all day on weekends, a nice bonus for us, as we had a rental car. At other times, it's mainly metered with a two-hour limit.
The service was occasionally a downside. When we first arrived, we were with our dog, and we were assured the "dog welcome package"(bowls, bed), would be waiting for us in the room. It was not, and we had to call four times to get it. We also had to call twice to get robes, and when we did, the wrong items were brought. I got the impression there were very few housekeepers Although the rooms were clean, some days there would be no washcloths, on others no replacement toiletries such as shampoo, and once the robe was taken but not replaced. Also, the door to cabinet that hides the mini-fridge was broken, and we had to call twice to get that fixed. Some of the furniture was a bit dinged, but we did have a very spacious room with two lounge chairs.
Further, the front desk did not always seem to give out full info. For example, we were not told that the passwords for free Internet in the lobby would work in the rooms once you logged on, so instead we spent $40 in internet charges. Also, the staff did not really explain the hours/days of the Executive Club, and oddly, it turned out to be closed Monday morning when you might most need the coffee and breakfast, and was unexpectedly open some evenings. (We had never used this at any Westin.) However, the food in the club was good, and there were a few items suitable for taking "to-go.)
Finally, we were told that our Starwood number was entered into the system, when actually it was not.
Anyway, there were some issues, but most of them are fixable, and for a short business stay it could be quite a convenient and quiet hotel.
