Bed and Breakfasts in France are known as Chambres d'Hôtes (guesthouses). There is a huge range of properties throughout France. Typically they will have between 2 and 5 rooms generally with ensuite bathroom. Depending on seasons and location, prices can be as low as 40 Euro per night double share with breakfast. Many Chambres d'Hôtes offer dinner for a little extra. There are some wonderful old town houses, mansions and even chateaux operating as Chambres d'Hôtes throughout France.

A rough idea of the main regions of France is useful in chosing the property that suits you.

Bed & Breakfasts are mainly found in rural and regional areas so generally speaking you will need to be self driving to experience this form of accommodation.

Many B&B operators speak English and some are even Australian owned and operated such as Anges-Gardiens (Guardian Angels) near Beziers in Languedoc-Roussillon.

Self driving is generally the best way to go to experience B&B accommodation although travelling around by regional railway would take you to a lot of smaller towns where B&B would be an option.
