Hi Nina,
You'll probably get many responses to this query. We've only been to that area a few times, but never to the former. It apparently has a killer market plus a river that runs through town. But its popularity means large crowds. Gordes attracts plenty of tourists for its quintessential 'lovely setting'.
We've rented in Apt (large and with good market) and Lourmarin. The latter is pretty, popular and has what we feel is the best local weekly farmers market--world-class cherry tomatoes and best-ever lemon pie just for starters.
Cucuron and also the obvious Roussillon make great daytrips. The former has an unmissable ancient water tank surrounded by cafes while the latter's rare tones are exceptional. Great place to experience a wedding at the old church. Bonnieux is another.
Pro tip regarding food & vin: Cavaillon's melons are hands-down the best on the planet and when cubed into say Beaumes des Venise white dessert wine are a foodic treat for the ages.
I am done. the end
