We had a great stay at Yifan's place during our trip to DC! Superb location, minutes of walk away from Union Station, and the townhouse is in a beautiful, quiet neighborhood. The room was spacious, clean, and comfortable. Yifan and his mom were very thoughtful and accommodating, allowing us to store luggage before check-in and after check-out. Yifan replied to our messages very fast. Highly recommended.
