My very quick one-night-stay was pleasant and comfortable. I had a problem with my reservation (my fault, not theirs), and the front desk clerk was extra helpful in getting it straightened out upon my arrival.
I needed to use the business center late at night to print out some handouts for the next day's meeting. Again, someone at the front desk quickly came to help when I needed assistance.
My room was clean, the bed was comfortable. I didn't use any of the extra amenities during my stay.
The hotel was a bit of a distance from any of the DC area airports, and I believe a taxi ride is the only convenient way to get there. I would stay again if I needed to be in Bethesda, otherwise I'd choose a location closer to the metro,
