I stayed at Bertina's house for a week and she was just as friendly and hospitable as all of her reviews would lead you to believe. In addition to providing a nice room at one of the most competitive prices I've seen on airbnb for a metro-accessible area, she was more than happy to share her washer, dryer, ironing board, refrigerator space, and her home in general. She was my first experience with airbnb, and she has definitely set a high bar. I would strongly recommend her to anyone looking to stay in the DC area.
