We have stayed in many Airbnb's in many countries, and Stephane's place is one of the very best we have experienced. The location is absolutely perfect, the apartment is superbly equipped, and Stephane is a wonderful and engaged host. And Bordeaux is lovely.
A word of warning: central Bordeaux is very unfriendly to cars, especially for parking, so drop your rental car off *before* proceeding to the apartment. We tried to do it the other way around and had real problems. Stephane was very kind and accommodating of the consequent delay in our checking in, but next time we will do it differently.
