First up, the location of the apartment is amazing - it is a 5 minute walk from the Place de la Bourse (and the mirror pool) which is smack in the middle of the UNESCO World Heritage site area in Bordeaux, as well as the tram station. The Tourism Office is close by as well, so any bus tours, vineyard visits can be easily arranged.
Cathy's apartment is pretty cosy, ideal for a couple's getaway. Situated near the bars and restaurants on the Rue Saint Remi (I'd recommend Cafe Brun for drinks and cocktails) makes it very accessible for all your requirements. The shopping district is close by as well.
