Perfect place for a large family (we were 5 adults) to stay close to the center of Bordeaux. Bedding is comfortable, no outside noise. I would just caution if staying there in the summer that the bedrooms have no windows so it could get warm! (portable fans are supplied).
Bathrooms and showers are very new.
Internet fibre speed was very good but there is very little cell reception when inside the apartment (old buildings with thick walls!).
I don't think there are many places in Bordeaux that can host that many people at once so it's definitely recommended for large groups.
