I had a short stay with Christophe for 2 nights only, but it was very enjoyable! He is a very kind and attentive host and his apartment is indeed very zen. It is also very well located, close to the center (only 3 stops by tram or 15 minutes of walking) but away from the touristy parts. I really liked the breakfasts Christophe prepared - you just have to try all those delicious jams! If you're going by Bordeaux, I would definitely recommend staying with Christophe.
