The 11th International Workshop on 2D Materials


DATE


February 17 – 18, 2023



VENUE


President Hotel, Seoul




How to reach Hotel President

○ From Incheon International Airport

Take KAL limousine bus #6701 bound for City Hall and get off at Lotte Hotel. Hotel President is right next to Lotte Hotel.

From Gimpo International Airport

1) By Subway

Take Airport Railroad Train bound for Seoul Station.

At Hongik University station, change to Line #2 (green line) towards City Hall.

Get off at Euljiro 1(il)-ga station. Hotel President is 250 m from Exit #8 of the station.

2) By Taxi

A regular taxi will cost about 25,000~30,000 won depending on the traffic condition.

The black ‘deluxe’ taxi will cost about twice as much.
