Kursk Station is the Moscow terminal for trains from central Russia (Kursk and Nizhny Novgorod), eastern Ukraine (Donetsk and Kharkiv), and some Sapsan high-speed trains from St. Petersburg. The Kadashevskaya Hotel is around 4 km from the station.
By taxi
It should take around 15-30 minutes to reach the hotel by car, although the trip can be much longer at peak times. If you are willing to negotiate with a driver on arrival, taxis should cost no more than $25. If you prefer, you can book a transfer with a driver to meet your train here.
By metro
If you prefer to use public transportation, take the metro from Kurskaya Metro Station and travel one stop west on the dark-blue line to Ploshchad Revolyutsii. Change there to Teatralnaya and the dark-green line, and travel one stop south to Novokuznetskaya, which is around 500 m from the Kadashevskaya Hotel.
