I tried trivago as a PRO user. I received not one booking in the whole year via trivago. I wanted to cancel but it automatically renewed before I knew it - with no alert. I contacted trivago and the online robot just keeps telling me I have to pay for another year. It is not acceptable they failed to deliver anything. I looked at the website and it is impossible to find where to cancel. If you are a small business trivago will eat you up and bleed you dry for absolutely no reward.
