I hear about loads of people who have apartments/villas who want to rent them out to help with the costs. I know that people advertise in the small ads, but is there any websites that offer this facility.
I found some UK ones which were great as the owner rents direct to the public, therfore cutting out agents fees etc, however they are in sterling.
I don't know of a specific Irish site but there are Irish owned apartments advertised on this site where you deal directly with the owner ( you can tell from the phone numbers ) http://www.holiday-rentals.co.uk/
