Ivan Bezdomny’s route
The route of the chase: Patriarch’s Ponds → Spiridonovka → Nikitsky Gates → Arbat Square, then the Arbat lanes, Kropotkin Street and Ostozhenka.
The place of the jump into the river is Prechistenskaya Embankment opposite Savvinsky Lane.
Conclusion: the route fully corresponds to historical Moscow. No errors.
