If you're looking for a place that feels like home, this is the place! :)
I love the small details in this house, the cleanliness, and the tidiness of the house.
I do not find any negative experience here, third-floor room without a lift is not a problem for me, but maybe yes to some of you who carry big luggage.
Location-wise, it is walkable to Columbia Heights Metro (ard. 5 mins walk) and to the bus (go to left and only 2 mins walk). Walk 10mins you'll find Giant Food. If you go to BWI airport later, take a bus to Union Station and go to BWI by Amtrak train (only ~14 USD for the lowest price). To go to museums' locations, you can rely on Gmaps.
Comfort-wise, I wish to stay here longer. There's one neighbour who likes to scream from his window, but we need to be compassionate that everyone has their own battle. As long as he doesn't harm others, for me it's fine.
Cooking-wise, all utensils are complete. I think this house has the most complete utensils amongst other Airbnbs I've ever stayed in. Cooking can save money a lot. Thanks for providing it.
So, 5-star for this place (from my genuine opinion) :)
