I stayed here during a business trip to Alexandria; my husband came with me. The location is excellent for Alexandria itself--across from the metro (only two stops from DCA) and a short walk to the quaint King's Street area. The lobby area and lounge are very nice. As with other Embassy Suites, there is a manager's reception with complimentary softdrinks, beer, and wine; there is a charge for cocktails, but it is slight (something like $2.50). The breakfast buffet has a good variety of made-to-order options beyond omelettes.
The room itself is fairly standard for ES, with the bathroom being just slightly smaller than others I've seen in ES. I would consider staying here again for another trip to Alexandria. Since it is located across from the metro, it would also be convenient for DC.
