Vincent was great. He was very accommodating to let us drop our bags off early while the place was being cleaned. He showed us everything in the apartment and has a book full of restaurant and wine bar recommendations, gave us a run down of Bordeaux via a map and taught us a bit about how the public transportation works.
The location is just on the south edge of the "historic" area and close to the river, so we always knew just to walk north to find everything we needed.
It is located on the 3rd floor by steps. We didn't have a problem with that at all but someone who can't easily get up and down steps might have an issue with it :).
