I live one block from the Stadium Armory Metro, and agree with the first commenter. while it is quickly becoming far from a good “investment” as i’ve seen prices skyrocket, it is more bang for your buck and i feel very safe there. i also agree that i prefer the area around stadium/armory to potomac ave metro, although having the harris teeter there is nice. eastern market is the prime location, but the prices start to go up. i don’t think you can go wrong on the SE side at all, and on the NE side if you are ok being further from the metro, has some lovely areas near H street and up towards trinidad that my friends all love. good luck!
