Superb berth in the city centre. Beautiful city, loads to see - go to Rubens house and the Fine Art Museum where there are lots of major Rubens and other works, a bit of a walk but well worth it. Lovely old centre, great cathedral.
Great selection of things to do, berth within walk of city centre, or get a tram - top tip is to but a 24 hour ticket. Hermitage museum excellent, as is aimless wandering.
