Air BnB, Homeaway, Owners Direct ...

[JammingtonDodger]

... anyone got any good links to other similar websites for holiday rentals? I feel like I've exhausted everything on these ones!

www.holidaylettings.co.uk/
But their commission can make holidays more pricey. If you find a good place google the name of the villa as you may well find it cheaper on Owners Direct or on the owner's own website!
Where are you planning to go? There are some rental sites for specific countries e.g www.cheznous.com/ for France.

Wimdu

Holidayfrancedirect.co.uk

That one gets you 20% off Brittany ferries crossings

Or if you're thinking of Spain there's www.spain-holiday.com/

Tripadvisor. But it looks like the big ones are buying out the smaller ones so there are fewer sites around.

Which country?

Booking.com, then change your search criteria to apartments and holiday homes.

We regularly use HomeAway and HolidayLettings with no issues

I've used vrbo.com with good results, and also the Alastair Sawdays listings.

Thanks, I'll try these. It's Italy.

If you're interested at all in Tuscany, I loved our week here:

I'm not sure they list with anyone else.

I hope you find somewhere great!
