Katja’s place is exactly as described; better, actually full
of thoughtful little touches, all personally curated. Don’t be put off by the apparent distance from Mitte, Charlottenburg - it’s a small city and the transport is excellent. You could even walk.
Katja is a kind and generous host. She went out of her way to make sure I got the key, and put up with the social awkwardness of my schedule meaning we didn’t actually meet until the day I left!
