The pictures don't lie. Katie's is an aesthetic treasure, a really cool place to live. It's spacious and light, multi-textured and still harmonious. I was there for two months. Everything works and when I arrived all was clean. Anything that I needed, whether information or some need related to the apartment, Katie quickly provided it in the most helpful way. She even turned me on to her doctor when I required a medical visit. The neighborhood is dense and varied. All sorts of people, architecture, vegetation, vibes, restaurants, coffee shops, stores, street markets. You discover something new each time you wander. If you want a rich Berlin experience and a very cool place to stay, I recommend Katie's place.
