The apartment is less than a 5 minute walk from the bus station that takes you into Bordeaux for 1.70 euro (at time of writing) and there are buses every 10 minutes.
Nana was super friendly and welcoming the entire visit. She gave me a bottle of water when I met her after seeing how exhausted I was from the Bordeaux heat and even sorted out a later check-in for when I realised I was running late.
I fully recommend this accommodation for anyone visiting Bordeaux!
