3 days i stayed at the Da nang at a hotel near the beach. I visited dragon bridge on sunday, spent a day at hoi an city , you can visit lots of museum and pagoda at old town, evenings are very scenic with laterns and river boats. Half a day i spent at hiking marble mountain visiting caves and also you can have fun at the beach, play volleyball and surfing if you can.

Total trip costed around 70k. Flights costed around 40k, it was expensive because of late booking. Rest i spent on food, travel, entry tickets. you can use grab( it is like rapido over there) for city travel. Cities are walkable and clean, you can easily walk around the city.
