Our room was locked on level 37A. It was a strong smell in the room that we couldn’t figure out what it is. We tried to open the window to get some fresh air, but it didn’t help. After 2 days of suffering, we did inform one of the receptionist staff members, his name is Dang, it was a wasted if my time. He promised to provide us some air freshener or move us to another room, and yes, the air freshener never arrived nor we heard or see him again. The worst experience ever. The system of two hotels- Panorama and The Empyrean Nha Trang are very confusing and chaotic. It was not a pleasure stay at all.
