I have stayed at the Lorien Hotel and Spa in Alexandria multiple times over the years, most recently for 6 nights while attending a conference. The hotel is a boutique hotel with an excellent restaurant, a spa, and a free wine reception from 5-6pm. It has meeting rooms and is able to host private dinners. I really enjoy staying here, As a Kimpton-In-Touch member I received free WiFi and $10 towards the mini-bar. The hotel is a short cab ride from the DCA airport (although you can take a train too). DC is accessible by taxi or the Metro (which is inexpensive and fast). Old Town is very quaint with lovely shops and excellent restaurants. All of the DC sights are accessible via the Metro. I had a very enjoyable stay at this hotel as usual!
