It is possible to walk to the Kremlin from the Aquamarine Hotel in a little over 20 minutes. The simplest way to do so is to exit the hotel onto Ozerkovskaya Naberezhnaya and walk north along the canal until you reach the third bridge (Bolshoy Moskvaretskiy). Cross the bridge onto Red Square, cross to the north of the square and turn right into the Aleksandrovskiy Garden. Cross the garden diagonally to reach the main visitor entrance to the Kremlin in the Kutafya Tower. If you prefer to use public transport, walk ten minutes to Novokuznetskaya Metro Station and travel north on the dark-green line one stop to Teatralanaya.
Change there to the red line and head west one stop to Biblioteka im. Lenina. The exit from the metro is directly opposite the Kremlin main visitor entrance.
