Ideal hotel for tourists
The Fairfax at Embassy Row was perfect for our family of five. We were a bit nervous about the location, however this hotel turned out to be ideal. The staff was very accommodating and there were other families staying at the hotel. 
The architecture of the buildings in and around the hotel, mostly embassy's, made the trip for is. This was our first trip to Washington DC and Dupont Circle is how we thought it would look.
It is a very safe area. The Metro station is just a short walk. Tip. Buy $20 worth of trips on the Metro card the first time you travel by train instead of buying tickets for every trip. 
The local restaurants and nightlife are great and there is a 24 hour pharmacy just a short walk up the street. There are numerous places to get your clothing washed for less than the hotel might charge. Visit the "Society for the Cincinnati" museum just next door to the hotel if your a history buff. Donations accepted. It's one of the best kept secrets in Washington DC.
Try the hotel bar for a romantic interlude. The atmosphere is soothing and the service outstanding. My teenage children and wife spent many hours in the gym.
