Very fast contact - host lives on the other side of the fence, so you can reasonably expect that he will be helpful in case of any problems.
Duplex is small, but cozy and very well equipped - everything that is written in the description can be found inside. There is some minor trouble with the internet (i.e. it did not work inside our rooms, we had to sit outside).
One can quickly reach Bordeaux city centre - place is in a short walking distance of a tram way that can bring you to your destination in 10 minutes (or shorter, I can't recall exact time-length)
Nonetheless, I recommend Xavier as a host in Bordeax - very much value for not that much money.
