Getting to INR from Orlenok hotel:

Exit from the hotel to the Kosygina street. Turn right and walk to the first (small) street which goes to the right (it is Akademika Zelinskogo street). Turn there and walk until the street reaches Leninsky prospect (a very wide street). You will see the hotel Sputnik to your right. From Sputnik, follow the map (you will have to cross Leninsky prospect; the traffic lights do become green for pedestrians from time to time, though quite rare!)
