sites to book a villa on?

[fredfortoday]

Please can someone suggest some good sites to book a villa abroad for a few weeks over the summer? Thanks very much.

CV Villas

Villa plus is who we booked through this year. Used them in the past and whilst its a wee bit more expensive than going private, at least our pool won't go green (long story) and we get a table tennis table and pool table thrown in.
