Ben and Duong are very open, lovely and friendly people. They accompanied me to many awesome places in Saigon and invited me to join the parties with their friends. I had a very enjoyable time with them. I'm pretty sure it's the best way to know Saigon well and fast from both foreign and local perspectives, to experience the real life in this city as a common resident other than just a passer-by. Hope to see you again, thanks for everything.
