Which is the nearest metro station?

The Moscow Marriott Grand Hotel is one block (a little over 100m) from Mayakovskaya Metro Station. To reach the station, turn left out of the hotel up Tverskaya Ulitsa and walk through the underpass at the next corner. Mayakovskaya is on the dark-green Zamoskvoretskaya Line, two stops north of Teatralnaya (for the Bolshoi Theater and Red Square).
