I was placing an ad to rent out a room in my place. Flatmates withholds all messages from potential customers unless we upgrade our account and pay them more money(especially for Early Bird). After upgrading my account, over half of the customers who contacted me were no longer interested. I do not feel that upgrading my account is anywhere near worth the money. You feel like you are selling your product at a loss if you even want a sale, and there are other websites out there that are cheaper and easier to use.
Flatmates will incorrect publish your information unless you have typed it out yourself. Do not use any of their templates. For example, 'all bills included' gets shown to the public as 'internet bill included'. Flatmates even tried to argue back saying that 'internet bill included' does not imply that other bills are not included. How is the potential customer supposed to interpret that when reading it?
On several occasions I have tried to contact Flatmates to ask for additional questions and clarifications. The responses have always been hopeless and do not actually answer any of my questions. I do not know how useful the website is for tenants looking for a room, but I have to post what my experiences have been like trying to use the website to find a tenant.
