This was our first time using the services of this company. The quality is good relative to the price. The seats are clean, the seats are lowered to a reclining position, a bottle of free water (charging was working on one side of the journey, but on the same bus in the opposite direction it may have been turned off.). In one direction the bus was delayed for an hour, in the opposite direction it arrived on time. Air conditioning is strong (if you are worried about your health, take warm clothes). Sometimes people take seats right in the aisles. We bought the ticket in advance through Vexere and paid at Winmart. Very comfortably. (We drove along the route Nha Trang - Ngoc Hoi and then back on the same day)
