(CBS News) When real estate people talk about "location, location, location," Blair House has it all. The historic stone building -- across the street from the White House -- is where foreign dignitaries will have lunch after President Barack Obama's inauguration.

The house is the president's guesthouse for heads of state, as well as kings and queens, when visiting Washington.

But what's inside and has happened there? For security reasons, reporters rarely get a look inside, but Ambassador Capricia Marshall, the Chief of Protocol -- whose office maintains Blair House -- recently gave CBS News a tour.

Take a look inside with CBS News' Margaret Brennan. Watch the full report in the video above.
