The rooms are renovated, clean and spacious. The bathrooms are clean but cramped. Speaks to the age of the hotel. I found my room to be quiet and a nice escape from the hustle of DC. The concierge lounge is OK at best. I enjoyed the bar and the bar staff was superb. In my stays I have not used the restaurants, preferring to get something on the go or nearby.
The Crystal City metro stop (yellow line) is only a few steps along the street. Using the underground walk via the Crystal City shops is a little bit longer, but still quite convenient.
There are numerous bars and restaurants within an easy walk. Walking back to the hotel around 10pm has been uneventful.
However, many of the shops in this end of the Crystal City Center are closed. The shops closer to the Marriott Gateway are better.
