Transportation access into and out of Bangkok from here is easy and there are good connections to the Eastern Seaboard. There's easy access to the rest of the city by road, and while there's no Skytrain it is very well served by the MRT underground (its North-South portion follows Ratchadapisek Road).
There's a ready supply of inexpensive taxis available at any time (just tell the driver 'Raht-cha-dah' - everybody abbreviates - and quick, easy access to the new Suvarnabhumi airport.
