We stayed at Nathalie's home for three nights.
It is perhaps the best place we have stayed in on our trip. The main feature that we liked was the ability to just sit in their beautiful garden and be completely relaxed.
The other main features for us was the comfortable beds (actual and sofa bed). Thankfully there was air-conditioning, a good shower and stove.
There are good transport links near to Nathalie's home (4 and 24 bus) all less than 6 minutes walk away, they take you into the heart of Bordeaux.
Also the information provided to us was great.
Only thing to watch out for (not a fault of the host or home) is the mosquitos.
Overall I would definitely stay there again and will be recommending to all my friends and family.
