Hostelworld " Featured Listing "

Hi guys, I'm about to apply for the hostelworld featured listing advertised but them in the HostelWorld->Marketing tab accessible from backpack on line.
Does anywone have some feedback regading the performacies of this service?
The claim that featured listing get an average of 3 times more booking, is it true?i want to make sure first since this is gonna cost 1'500€.

There is also another possibility to featured listing also on rynair(a part from the normal listing) but this is more expensive.

If you have any experiance or ear about it just drop few lines! :cool:
