Hi,
I used Owners Direct but have changed to Holiday Lettings.
I changed from 'money up front' to pay as you go where I only pay for the advertising if it is successfull.
There are two more big advantages. They are linked to Tripadvisor so not only the advert is also there, the feedback system is also linked. The second is that they manage the money, accepting credit card payments. I have had one booking through them and was imppresed with the way this worked, including taking and refunding the damage deposit. This was is far better from both sides preventing fraud.
Setting up the advert was easy eough but there was some dirfficulty in getting the title as I wanted it and also the location as Los Alcazares - Roda Golf, this was took two or 3 email conversations to sort this.
