My wife, 2 lads (13,11) and I stayed here for 6 nights and loved it. From the very first greeting by the jolly doorman on the welcomingly charming entrance we felt at home; the Reception/Concierge service was exemplary, nothing was too much trouble and the fine line between professionalism and approachability was trodden expertly.
Our room - a dbl dbl - was lovely; if I had one minor quibble it would be that the AC was a bit on the noisy side. However, once turned off at night it was fine and the room remained cool - we simply put it back on during the day whilst we were out.
The location was terrific, just a few mins down the very pleasant Massachussets Avenue from the lively DuPont Circle (shops, restaurants/cafes, Metro Station).
For the slightly more energetic you are only a 20 mins walk from the White House/Mall/etc (and that was at the pace of surly teenager!) in one direction, and a slightly shorter jaunt to the lovely Georgetown.
The hotel also offers a nice intimate bar (if a tad on the pricey side - a treat to end your day with a well-deserved beer/cocktail!).
I would recommend this hotel in a breath, great for young families and couples alike.
Thanks go to the lovely management team for making our stay so pleasant.
