Not worthy of the Marriott name
We recently stayed here for business. This hotel was not primarily a Marriott property and it shows. The lobby is on the second floor and is tiny. Our room was fine but we had unbelievable trouble with their Internet service. Many times we had to give up as it was unusable. Every time we called the front desk about the Internet, they gave us a different excuse. 
Although there were security people on the lower floor where we entered, we still did not feel safe arriving at this hotel. The only good thing for tourists was the Metro station just yards away. We had a car which cost us $33/night for valet parking (the only option available).
This was the most expensive Courtyard we have ever stayed in. We would not go back.
The only places to eat nearby were fast food places.
