hello! I'm new member. nice to meet you..
It costs about $18 for a taxi.
I booked that service 2 days before. They charged me 17$.
Actually, the taxi cost about 15$-19$ depends on taxi branches and time to pick up with a litter higher price.
price vary from 10-20USD. check hotel for better rate
Yes, if you bargine and if you don't need alot room for your luggages so just need small taxi, it is like Martit
probable cost 300.000 VND for one way.
Last month, I went from from Old Quarter to Noi Bai airport last month. They charged me 15$. I think they will charge more for foreign people. But Its price must be from 15$ to 18$.
Fixed price is 17 usd per private ride at the time of writing. Updated of hanoi airport taxi fare can be seen at www.noibaiairporttaxi.org. Hope this helps
