Hi there. I'm a single, 29-year-old male heading to DC for the first time March 27-30. I haven't booked a hotel yet and need some suggestions on where to stay. I'm looking for somewhere $80-100 a night, clean, within reasonable walking distance from a Metro station (doesn't matter which one), not in too bad of a neighborhood, has some eateries/bars/pubs I can walk to. That's about it really. Any suggestions gratefully appreciated. Also, what time does the Metro run until?
