We flew into Reagan National Airport just two stops from this hotel. It is very convenient to all the main attractions in DC. It's on the blue and yellow lines for the local WMTA rail line just one stop from Arlington cemetary, and two stops from the National Mall. You can actually see the Mall right across the Potomoc as well as the Pentagon and Arlington. We even took the rail down to Alexandria and caught a boat to Mt Vernon. No car needed!
The hotel itself is pretty basic. We did find that the rooms were generally okay with a few flaws. Someone had slammed the door so hard it left a hole in the drywall, and the smoke detector was hanging by its wires. We notified the desk and they did offer us another room. Otherwise the rooms were clean and good enought for our purposes. Surprisingly, there was no noise from the outside world. The airport and the highway were very lose, but you would not know it. The pool on site is not very deep, more for small children. The staf is great! Very helpful and attentive. I would rate them five stars! Breakfast is included with your stay which was good. Other dining is pretty limited in the area other than the shopping mall a couple of blocks over. Again, a quick train ride and you are right in the middle of a lot o restaurants. This is not a place for those seeking nightlife. Most of the guests were military personnel or others visiting the Pentagon across the road or Homeland security.
Overall, a nice stay. Nothing luxurious, but a good place to rest your weary family at the end of the day.
