There are smaller shopping centers in Danang. Big C is an older one in the middle of the city. Because of it’s location near the hotel and apartment complex, this may be close to your location.
Big-C is an old fashioned discount store in Danang. Be careful of this website. You can get lost in the multiple city, multiple location, multiple language options. Big-C may have a membership card. If so, it probably is worth getting.
