Geraud is one of the best hosts I've stayed with! He showed me nice places around that you probably wouldn't easily find in guides or travel books, we spend great time having a chat and a glass of wine and he helped me a lot with everything. The place is not far from the center and can be easy reachable by bike, train or a bot and a room itself have everything necessary to settle.
I highly recommend his place and will definitely try to stay there during my next visit to Bordeaux!
