Use with care to get a good deal
I have used Agoda several times in the last year. What I liked is that it is possible to find lower prices than booking directly or using other online travel agents. However, I find the website's layout confusing and it uses pressure tactics to push customers to book quickly (x people have already booked or are looking at the same deal, there are only x rooms left at this price, etc.). Agoda promise to match any lower price that you can find after booking with them. Don't count on it, I booked and a few minutes later they offered a lower price, but their customer service refused to refund the difference on a technicality. My advice is to do your research before using them and to study the deal carefully before accepting.
