These three mainline stations, where trains arrive from St. Petersburg, Tallinn, Helsinki, Central Asia, Vladivostok, and Beijing, are located on Komsomolskaya Ploshchad, a little over 7 km from the Katerina City Hotel.
By taxi
If you plan to negotiate a taxi on arrival, you should not pay more than $25 for the trip to the Katerina City Hotel. However, it may be easier to book a transfer with a driver to meet you off the train, which you can do here. The drive to the hotel should take around 20-30 minutes.
By metro
Komsomolskaya Metro Station is connected to all three stations. Take the brown circle line and travel clockwise three stops to Paveletskaya, which is only a five-minute walk from the hotel.
