Really easy to find. The Cathedral was closed when I went there but I wasn't interested in going inside anyway. There was some young Vietnamese lads playing football outside until one of them occidentally kicked the ball over the metal fence surrounding the Cathedral. It was funny to watch. There is the typical Hanoi restaurants and cafes on the other side of the road so definitely come here and spend 15-20 minutes enjoying a coffee or something to eat and take a few photos of the Cathedral.
