Great location and great hosts. Columbia Heights offers everything you want and it's well connected to downtown and other areas. Mike and his family are friendly and promptly available in case of questions/needs. The flat is well furnished and spacious. I rented the apartment for 3 months during the Summer. Being in the basement, it's protected from the often unpleasant heat of DC but the drawback is the lack of sunlight, not great for home office.. Overall I enjoyed Mike's apartment!
