It is the same hotel they used in TAR13. It is a block from the train station to DME and just across the river from the train station to SVO. It is a pretty long way to Sokolniki Park in NE Moscow. With the taxi situation in Moscow, it is probably a safer place for them to get a taxi to the airport than out in the sticks, so to speak.
It is the same process they used in TAR13. Pit stop in NE Moscow and Pit Stop release near the Swissotel in downtown Moscow.
Or Production could just be lazy and not want to mess with Moscow traffic.
