We had a Groupon valid here and in l'Ancienne Auberge. The hotel is across the street(parking lot) from the main building; Georges Blanc has made the village of Vonnas a "village gourmand" and it is very beautiful and tasteful. This is the 3star establishment and there is nothing wrong with it, on the contrary our superior room was perfect. the staff were smily and helpful and did not even ask for a credit card upon check-in. The TV had many channels, the bedding perfect as were the closets and the bathroom strikingly pretty. But no bathtub...Lovely towels!!
The SPA was included with our Groupon, but one pays for the bathrobes. The pool and hammam and whirlpool are nice, the changing rooms too small. Of course if you are in the 5star part of the hotel you walk down in your bathrobe so this is not a problem. the pool is at 26 degrees. In summer there are two other pools, one without kids.
Breakfast is down the street, the only downside but folks, it was absolutely excellent, with many desserts and cakes, eggs made to order(don't be shy, esp for 28 euros!) a Nespresso machine, superb thinly sliced cured ham, all manner of yoghurts, all this served in a tasteful bay-windowed rustic large space.
