Simply the best tour we have ever booked on ToursByLocals! Khoa is a genius: very smart, efficient, happy, and a great singer as well! We loved everything on this tour: the Cu Chi Tunnels, the lunch we had in Ho Chi Minh City, the Central Market, the War Museum... it's a great tour for those who are on a cruise ship, and you can't get a better guide than Khoa! The van he rented was also very nice. We loved everything on this tour. Congratulations, Khoa!
