This passage is super short but probably the most picturesque in the Old Town. Two arches between houses and intense colors make it look like in a fairy tale. There's a wedding palace just around the corner so it's not unusual to see just married couple walking down this street.
If you want to escape the crowds in the Old Town yet still feel its unquestionable charm this is the place for you. Be sure to also walk down the steps to the small square from where you can admire a nice view over Vistula and to the other side of the river. Not that many tourists get here and you often can have the place all to yourself
