A very disappointing experience for the receptionist, no customer guidance but an arrogant attitude, the room was very clean and the location was suitable. I arrived at the hotel and rang the bell, waited a bit long so I rang it a second time, and then I was reminded "the first ring is enough", I said I was standing in a hidden corner and didn't see him come out so I rang it. After that, he still spoke with a bad attitude, when I checked in, he acted like I was staying for free. I paid to stay, not to receive such an indifferent reception. I will never come to Cozrum at 135/4 Nguyen Cuu Van again.
