Which is the nearest metro station?

It is only a couple of minutes' walk from the Heliopark Empire Hotel to Belorusskaya Metro Station in Belarus Rail Station. To reach the metro, turn right out of the hotel and walk to the end of Pervaya Brestskaya Ulitsa. You will find yourself on the square in front of the railway station, with an entrance to the metro station in the right (northern) wing of the building. Belorusskaya is on the dark-green line and brown circle line, three stops on the former from Teatralnaya, for the Bolshoi Theater and Red Square.
