Looking For a Holiday Home This Summer

We're currently looking to rent a villa / maison for a week towards the end of August not more than 2 hours (give or take) drive from Montpellier. We're 2 adults and 2 children and are looking to come in under 500 euros for the week for something with a garden. Countryside is no problem but we'd like to be in easy distance of a reasonable sized town for our shopping needs.

The amount of websites is incredible and sifting through them all takes buckets of time. Does anyone have any websites / recommendations / spare villa?
