We stayed at Sarah's place for one night at the end of a great weekend trip doing the wineries around Saint Emilion and it was perfect.
We were a group of 5 friends but there was easily enough space for all of us with the 2 beds and the fold out couch.
The deck was a great area to use even though we didn't spend much time there. The bathroom was extremely modern and spacious, and the kitchen was too.
It was an easy walk to the pedestrian part of Bordeaux, which is absolutely beautiful.
I would definitely recommend Sarah's place as a great base to stay when visiting Bordeaux.
