Dont book reddoorz or Oyo via agoda.
My advice is to book only hotels at agoda if they are directly provided by agoda . If you see other labels like reddoorz or oyo you dont always get the hotel room at arrival . Or you can be transferred to another cheaper hotel. In both cases you are not notified before . those cheap other organisations dont help you. I had problems to complain online to agoda with their chatbox and old email adres did not work . But pissed of consumers website has correct adresses . Now after 1 week most of my future problems are solved by agoda . But i had 5 days in a verry bad hotel provided by reddoorz and being angry to that situation ruined my holiday . For other part , agoda has often the best offer. They belong to same organisation as booking.com and priceline and kayak but each can have sometimes also sharper rates. So stay surfing.
