A straight line is a reference point, not a route. By road, the departures terminal is 9.7 km from Băneasa-Sisești, about 14 minutes by car on the DN1 in light traffic, ~13 early in the morning and up to ~20 at rush hour.
The two Arkadia apartments in Băneasa-Sisești are about a 15-minute walk from the Enayati Medical City campus (some 800 m in a straight line) and under 4 km from the other hospitals and clinics of northern Bucharest. Here is what you will find in them, who they make sense for, and who they do not.
