I used to live in Berlin and can tell you that Jay and Kati’s place is in a primo location in a hot area of town. Shops and restaurants right outside the door and very, very well connected via public transit. I enjoyed the bakeries around the corner every morning for breakfast, the outdoor markets, and good restaurants. Jay and Kati are also very pleasant and interesting to talk to. The only thing I might note us the apartment is on the 5th European or 6th American floor and there is no elevator. But then again, in this area, most places won’t have an elevator. Just beware if you have troubles with stairs or have a lot of luggage. I’d definitely love to stay there again, stairs and all.
