Not matter for how short a period you are in Moscow, a ride in the Moscow metro is a must experience. Make sure that you choose a time which is not a rush hour as it is next to impossible to enjoy the beauty of the city when it is crowded. The metro takes you to all the major corners of the city. The best part of the journey on Moscow metro are the magnificent stations that come along. A couple of good enough to be mentioned are Kazan'skaya and Mayakovskaya.
