Doubletree on Rhode Island Ave was a hit
We got an excellent price at this hotel so we took the opportunity to see DC. The location was fairly convenient - located the same distance from 3 different Metro stations - Farragut North, DuPont Circle and McPherson Square. On our last day, we discovered a bus from Rhode Island Ave and 14th to the Washington Monument - the #52. The hotel restaurant is pricey but a one block walk away was a Whole Foods with an excellent array of breakfast in the morning and dinner at night. DuPont Circle offered several restaurant choices. We felt very safe in this yuppy urban area.
The hotel room was more than adequate for our needs - clean, comfortable beds, well-supplied coffee-maker, and copious hot water in the somewhat small bathroom. I know previous reviewers have complained about the lack of space but we were up, showered and off to start our day by 9am and were rarely back before 10pm. I have no hesitation recommending this hotel to anyone who needs a reasonably priced hotel in the DC area - not in the tourist district but only a 15 minute walk from the White House.
