Hidden gems in Amsterdam: Little houses

Westerstraat 70II - little houses in Amsterdam
Hidden gem in Amsterdam are these little houses. How do you think they look like in real life? How big/small are they?

You’d probably gotta go there and check them out by your own eyes.

I would never forget how cheerful I was when we discovered these seven little houses secretly laid on top of one another in the gap between number 54 and 70 in Amsterdam’s Westerstraat.
