I agree with Mosaic, a gite is usually let out for a week minimum and they are usually family size with would be far too expensive for a couple. Next up from Formula 1 hotels and in similar locations are Etaphotels which are a bit more expensive, but not much and more likely to have vacancies as the immigrant workers tend to go for the F1s. A cheaper option than either of the above are 'gite d'etap', these are a bit like youth hostels but privately owned and may have male/female/mixed dormitories and meals available. The F1/Etaphotel do breakfasts but pedestrian access to town centre restaurants is sometimes a bit of a hike.. Alistair Sawday does a good book listing B&Bs in France. If you get into northern Spain,the Hotel Risco just off the motorway on the N634 into Laredo is very good with an excellent restaurant secure parking and a panoramic view over the town and the sea( I once stopped here on bike trip tp Portugal, and a car trip to Santiago de Compostella).
