Perfect for am extended stay with kitchen and laundry and plenty of space for our family. Appreciated the extra toiletries. Plenty of towels. Nice to have a parking space right out front.
The only drawback is yes, you'll absolutely need a car as it's not within walking distance of a metro. So we would drive a few minutes to one and park every morning. Washington DC roads are a pain and the gps directions lagged about 30 seconds. Because of all the crazy round abouts and turns, we used GPS every single time. My husband and I logged about 6 hours each of Google maps time (some for figuring out the metro).
For future guests: We parked near the Pentagon City station in an underground Parking garage next to the Target and a Harris Teeter (Fry's Food sister store), perfect for grabbing groceries at the end of the day. $20 a day or less if hourly.
From there, you head down through the mall parking across the street and through the mall food court (you can walk through even at night after close, thank goodness). The Pentagon City station connects to the mall.
