Offers competitive rate
This is my first time I booked with Hotelopia. They offered the cheapest rate for the hotel rooms I booked. There were no issues during check-in/out, so I can say they are very reliable.
But I think the cashback processing took too long, it's been three months since my stay and I only got the cashback now. Nevertheless, I'm glad I got it as it just stresses how much I saved by booking with them.
