Mila is an excellent host. Not only did she go out of her way to make her waffles vegan for us, but she had tons of maps and recommendations, as well as directions for what's the best public transportation to use from her place. The location is about a four block walk from the Columbia Heights metro stop, and there are lots of buses that stop nearby. Other than at check-in and in the mornings at breakfast, we had complete privacy and the entry and upper levels completely to ourselves. It's an older building, but everything was kept clean and in good shape. I really recommend staying with Mila!
