How do I get from the hotel to the Tretyakov Gallery?

From Dostoevskaya Metro Station, less than five minutes' walk from the Slavyanka Hotel, travel south on the pale-green line two stops to Sretensky Bulvar. Change there to the orange line and continue south two stops until you reach Tretyakovskaya. The "Old Tretyakov" on Lavrushinskiy Pereulok is just over five minutes' walk from the metro.
