We stayed at the Best Western Rosslyn during the Presidential Inauguration, a time when everything was crowded. The staff went out of their way to be helpful (even cheerfully mailed us some items we left behind). Everyone at the desk was happy to answer questions and give directions. The room was very clean, though small. Parking is free. It's not a luxury property, but if you are looking for an excellent value in DC, with great staff, it's a good choice. It is very convenient to the Rosslyn Metro station and to the Circulator bus that goes to a number of neighborhoods and sites in Washington. We would certainly stay here again because of great staff, cleanliness, and convenient location. You can hear loud noise in the hall, a downside if your hall has party-goers.

Friendly Staff, clean rooms, comfortable king-sized bed and free parking. There is not a breakfast included with the like many Best Westerns, but the rest of the stay was good. Relatively close to the Capitol (about 6 miles) and walking distance to Arlington National Cemetery if the weather is nice.

This hotel is an excelent option to stay when you visit Washington DC or Arlinton.
It is quite simple, but have everything you may need.
The staff was very cool and helpful, giving me me a lot of tips about places and things to do.
A five minutes walk takes you to the Rosslyn metro station, from which you can reach almost anywhere in DC. Or, you can also walk a bit and visit the Iwo Jima Memorial.
Around the hotel there are many fast-food restaurants and cafes, and some other helpful stores such CSV, Walgreens, car rental...
Definitely, I would return there.
