I was trapped by the good reviews. It turns out this is a large hotel that has been dormant for a long time and is trying to revive itself, with facilities that I feel are still in their infancy. Hot water and Wi-Fi need to be set up first. At the reception, they still confidently display a price list ranging from 700,000 to millions, which I feel is far from appropriate given the actual situation.
Anyway, I managed to conquer myself by completing my booking today without disappointment.
