Nice hotel for adults, although not really a family place for young children. EXCELLENT if you're looking for somewhere to stay that's nice but doesn't cost $300 a night in DC. We came for a conference in DC, and picked this hotel because it was only $129 a night for two double beds, yet it was less than a 1/2 block away from a DC Metro station. We ended up buying $35 1 week "short trip" passes for the Metro, which allowed us to take the Metro from Regan Airport to the hotel, and from the hotel to the very entrance of the conference center, plus also to several different stations around town. We were able to get from the hotel in Arlington to the Conference center in DC in about 15-20 minutes.
There is no pool or spa, so not much for kids to do, but we were happy not to have screaming kids running the halls when we were there for business anyway, Rooms were nice, very clean and well kept, and had a refrigerator, which is always very handy. We ended up saving about $1200 that week by staying in this hotel, and never once had to take a taxi. I would certainly stay there again.
