It was the worst stay of the 15 days of my trip to Vietnam. The image was deceived like a sunny place. The room I booked smelled like an underground building and there was no sunlight at all. I wanted to get a refund from Trevlka, but it was not easy to connect with the counselor. Eventually, I paid an additional fee and stayed in a sunny place, but the employees were very annoyed by the conversation with each other in a derisive tone, knowing that they were foreigners who did not understand Vietnamese. Until now, I had only paid for Agoda, but I paid for Trevlka because it was cheaper, but all that remained was the feeling that I was deceived. I don't want to use this app and this hotel anymore.
