We stayed here after a week in Valbonne, and thoroughly enjoyed it. The house is located in the heart of the village, with Le Petit Cafe directly opposite. Communication with the hosts was excellent: Nicolas emailed us weeks before the trip with detailed instructions, and Thierry welcomed us on the day of our arrival. The check-in process was quick.
The house itself is incredibly charming and gives you the impression you're living in a castle. The layout can be tricky for very small kids (we had 1.5, 4 and 6 year olds) because the steps are quite steep so you need to watch out where they're walking.
The swimming pool, surrounded by fig, almond and olive trees, was almost as if from a novel: deep blue water (reasonably cool when we were there) that offered a refreshing swim and a fantastic view of the cathedral above.
The village is surrounded by vineyards and olive orchards, offering superb opportunities for walks or bicyle trips.
There are plenty of things to do further afield from Opede: everything worth seeing in Provence (Gordes, Bonnieux, Avignon, Menerbes, Lourmarin) is a 20-40 minute drive from the house. There are summer sunset concerts at the cathedral above the village - unforgettable - and fun events (tapas night + jazz) at Le Petit Cafe.
Previous renters left a few things behind here and there (espresso pods, olive oil, sun screen) so you really feel like you're staying in a friend's house.
We would certainly like to come back.
