Ive found the perfect spot for my next visit to Nha Trang: right in the middle of the hot streets, steps to the beach, tons of incredible food literally outside the door. $11USD/night you cant beat it, and you're not in a hostel dorm with 12+ people. I had booked a similar room in the city center (away from the beach/strip) for the same price the night before, and Apus was a MUCH better option.
Located right in the middle of the tourist/shops/backpacker/beach area, you cant beat the location. And all that considered, its not loud at all. Couldnt hear a thing from outside. Less than 5 minute walk to the beach & tons of restaurants, bars, shops, spas, EVERYTHING right around you.
Some of the staff spoke little English, but they were still very helpful with organizing a taxi transfer & even letting me in late one night when I came home at 2am from the bars.
The room was small but all you need for 1 person. Perfectly clean, safe, and cozy. Whole hotel was spotless clean, actually. Aircon & WiFi were both good, same with the hot water. What more do you need?
