Bertina is very welcoming and has a nice home. There isn't too much nearby, so the breakfast / snacks she provides are extremely helpful and convenient. The metro station and bus stops are about a 10-15 minute walk from her house, and the nearest food / store options are in that same area. The room that I stayed in and the bathroom that the guests use were both nice and clean. I would definitely stay with Bertina again if I was visiting DC.
