As others have said, the hotel is in a beautiful building in an excellent location. The guests rooms appear to be converted from large offices. Repurposing was done well, however, preserving many of the lovely architectural details. Despite the location, the room was quiet. It faced on an inner courtyard with a bar/restaurant with outdoor seating. I don't know how that would have affected the noise level because it was cold, dark and raining, but it looked lovely.
We opted instead for the fireside couches in the lobby and then dinner in the regular restaurant. The lobby was cozy, the restaurant a little loud - as are most places in DC - the food and wine great, and the service unrushed even though we arrived late. However, the kitchen had run out of the caviar for the trout rillettes I'd ordered. The chef offered to use another type - but only for an extra $3. The whole thing was delicious, with maybe 2 tsp of caviar. Still, I'm bemused by the belief that when the chef has to make a substitution the customer should pay more. At least they asked.
Checkout was simple and pleasant. I like this chain and will keep an eye out for its other properties.
