January in South West France - what to expect and where to stay

La Reine and I will be visiting South West France in January and, after a couple of days cat sitting in Saint-Jean-de Luz, we’ll be meandering our way back towards Limoges between 27th and 31st. We’d welcome any suggestions of where to visit and suggestions for B&B accommodation open at that time of year. We’re particularly keen on the area between Bordeaux, Rochefort and Angouleme but are open to suggestions.
