We stayed at the Embassy Circle Guest House for four nights during our anniversary trip to DC and I can't say enough about it. We loved it! We are not usually B&B people, but I wouldn't hesitate to book a room here again. The rooms were nicely furnished, bathrooms updated and anything you need could be found at the B&B. It felt more like staying at a home of friend then a hotel. No TVs in the rooms but we knew that before we left (and the conversations with other guest were much more entertaining!).
Breakfast, evening snacks and drinks were very tasty. Since we were there during the government shutdown, it was wonderful to have other guests and Raymond and Laura to talk with and find alternate plans during our trip. Every one of their suggestions was amazing (they know all the restaurants and best ways to get around the city).
Location wise-it doesn't get any better. Very close to the Dupont Metro station. Numerous restaurants and shopping nearby. A beautiful neighborhood for walking and seeing all the areas embassies.
We can not wait to return to this amazing B&B.
