I'd say this apartment has just about everything a DC tourist could ask for. I'm a senior (not high school) , who was traveling solo on this trip. I really felt safe in this beautiful, walkable neighborhood. The bed in the apartment is super comfortable and I slept like a log (not my typical even at home). I loved that Whole Foods was just a block away. Super convenient. There are also great coffee shops and a fabulous Greek restaurant just 3 blocks or so toward Union Station and to the left.
I would highly recommend a stay here and personally hope to return in the near future.
