Going to the city centre from the Klassis Resort Hotel, one can reach Taksim at most in 60 minutes if the traffic is not heavy. Two ways of transportation is possible to the Klassis Resort Hotel from the airport. If you use the E-5 motorway, driving from İstanbul towards Tekirdağ, one can take the Sahil - Sinekli exit, past Selimpaşa, and reach the hotel through the upper crossing.
The second way would be taking the TEM (Trans-European Motorway) after the airport, and taking the Silivri exits, and continuing from the point of connection with the E-5 motorway. Likewise it is possible to reach Klassis Resort Hotel, following the Sahil Sign.
