Probably the most famous room of the White House. The Oval Office, which is located in the West Wing, is the main workplace of the President. The windows are made of bullet-proof glass. Each President may redecorate the room as he wishes.

... Cabinet Room ...
The US President meets with his ministers in this room. The sessions are rarely held in the White House. The President sits always at the middle of the table, the Vice President sits in the Oval Office directly opposite him.
... President's Room ...
In the past, the room was used as a workplace for secretaries or the president himself. Today the room is used as a dining room.
The West Colonnade walkway, also referred to as the "45-second commute" by insiders, is used by White House staff to travel between the West Wing and the official residence.

... the Blue Room ...
Featuring blue upholstery, blue curtains, and blue carpet, the oval-shaped Blue Room has stayed the same color since 1837. Traditionally, the president greets state visitors here.
This center portion of the home is also where the first family has its private quarters. Here's a picture of the Treaty Room, where the first family gathered to watch the US women's soccer team in the World Cup Final.
