A city of identical fronts and entirely dissimilar interiors, which is the best possible arrangement for a directory such as this.
One entry does not need a whole day. It needs an unhurried morning and somewhere to sit afterwards.
Van Loon takes an hour and a half if you do it properly, which means walking to the end of the garden and turning round to look back at the house. Most people never leave the first floor, and the first floor is not the point.
The city is flat and walkable and the trams are a courtesy rather than a necessity. From the Keizersgracht everything in this directory's reach is twenty minutes on foot; the bicycles are the only real hazard and they are not joking.
Go in October. The queues at the large museums are somebody else's problem by then, and the small houses — which have no queues in any month — are lit the way they were meant to be lit.
