I have nothing but good things to say, I don't know where to start from.
The place is absolutely beautiful. What you see in the pictures is what you get. Brand new, clean, well kept, warm cozy feeling.
The neighborhood is safe and conveniently close to a lot. Some things were a quick cab ride away! Pretty central to everything you need. Walking distance from grocery stores, train/metro/bus stations. Berlin Wall is walking distance. There is a strip right around the corner with everything! Every type of restaurant, salon, shops, theater, cafes, etc...
Katja was amazing. She is so helpful and so sweet! Great communicator, if you have any questions or advice she is more than willing to help you out to make sure you have a great time on your trip. Thank you Katja for everything! You're the best!
