I am so thankful of Ms Mai for helping me throughout the journey. She was so supportive and save my money and time. I booked for nho quan, assuming that it is ninh binh only, but turned out a very different location. Ms Mai not only provided me free drop off to Ninh Binh, but corrected the pickup location to Ninh binh for mu return journey as well. Hats off to Duy Khang for such a great service and support.
