This is a very clean, chic, comfortable walk-up located very close to a variety of unique restaurants, popular bars, and cute shops. The neighbourhood is fabulous, and offers a decent choice of places to see and things to do -- I would highly recommend taking the short walk to Archipelago, a fantastic tiki bar. For those attending conferences at the Washington Hilton, the walk is incredibly short and very manageable.
The apartment itself is very stylish, with bright colour choices and tilework. The bathroom is huge and the shower is absolutely glorious, it accommodates tall people without any problems. The kitchen is also very nice, with ample room in the fridge and a nice little countertop coffeepot.
I would definitely stay here again my next time in DC!
