We then booked shared airport transfer bus that made us a bit nervous as it stopped in a lot of Hotels while going to Da Nang Airport. Luckily this airport isn't that big and it doesn't take very long to get to the plane. We then took the plane to Ho Chi Minh City (Saigon) . From the airport we shared a taxi to French Quarter with some people from the plane. Again we stayed at a very good capsule bed place named Eco Backpackers Hostel for 7$ you get 1 beer a day and a cool rooftop terrace. Ho Chi Minh City is quite modern but the traffic is crazy, there is scooters everywhere and except from parks and squares there isn't very nice walking streets so for a trip of only 15 days I recommend not staying more the a day. Except if you take the bus to Ben Tre 1,5h 70 000 dong to take a boat trip on the river.
