It hasn't been mentioned yet, but I should mention Crillon le Brave near Gigondas and Seguret. My husband and I go to Provence and Antibes every summer and always stop there. Lovely service, beautiful rooms etc.
We also love Bastides de Gordes.
I am not a huge fan of Oustau de Baumaniere, but I know several people who like it.
Aix is mediocre to me as far as places I love being in Provence, and Villa Gallici is mediocre.
Hotel de Tourrel is great for a night or two stay in St. Remy, but we always end up back at Crillon le Brave
Le Covent de Minimes is in a beautiful area, and has lovely service, but the rooms are not the best, but still a lovely place to visit.
