This place really makes you feel like home. The employees are friendly and helpful, and you can…read moretell that they're passionate about what they do. The look of the shop can come off as a bit chaotic, but I found it to be charming and authentic, and you get the feeling that it's always been and will always be that way.
I went in to get a few keys made and also to find a screw that was missing from a coat rack kit. They made the keys and told me to come back if they weren't working correctly, but unfortunately didn't have the screw I was looking for. They told me a few other places I could go, but to my surprise, a carpenter next to me told me he could custom make one for me in his shop. They all worked together to find a good screw to work from, then he gave me his card and I went to his shop and he fixed it right up for me!
In such a big city as Hamburg, it was nice to find a place with a "small town feel."
One note I should make is that all of my interactions were in German.
