We spend a great week at Isabelle's place. Apartment was well-equipped, with even some toys for kids.
Location was great, close to everything, and there was a tram station in 2 min. walk. Though the street was noisy because of the cafes and bars, but nothing extraordinary and we were able to sleep at nights.
Overall I would definitely recommend to stay at Isabelle's apartment if you are planning to visit Bordeaux.
