Catherine's and her family's house is easily approachable from the airport and also from the train station (Gare Saint-Jean), and it is within walking distance from the old town area.
Catherine and her husband are very nice hosts, I am grateful for their kindness and their helpful attitude.
The room is lovely, it was clean and comfortable, and there is also a pocket guide about Bordeaux on the shelf if you are not well prepared what to see in the city. :)
Merci beacoup!
