mid-range UK holiday companies for Villa Rentals

[omniflow]

Hi - trying to sort out my 2023 holidays - and I'd like to book a 2 centre holiday - Villa only - in Europe. I like to find nice places to stay and then plan the rest of the holiday around that. We would be driving from the UK. It would be really nice to find either flexible changeover days or 2 different companies with different changeover days, so that we can spend a couple of days driving from one place to the next.

There are 2 companies that I've used before - Simpson Travel and CV Villas / Travel - both companies are fine, but I'd like to have a bit more choice of destinations. I don't want to take pot luck with something like AirBnB or VRBO - I'd like to use a company that inspects each property. I know that this costs me more.

Any recommendations?
