To be honest, this is not the first time I've visited Bangkok but definitely one of the best experience ever with Swai. We can feel the passion he had in his work, he absolutely is a hardworking guide with a kind soul. Not only will he stop to offer assistance to lost tourists on the way, he goes way beyond what he is paid for. Swai would share his own experiences and additional stories he'd know about each attraction that you'll never know if you read them online. Thank you for the hardwork & patient, Swai !
