I interviewed at Howard last month and I was really impressed. A lot of people are missing out by not applying there. Anyways, the interview was very laid back, lunch was provided and they give you a list of places to stay that are not too far from the campus. The neighborhood itself is not that great, just like in most dental schools. It is really close to the subway and bus so transportation shouldn't be too much of an issue. PM me if you have any more questions.
