Katja's place in Berlin was perfect, as another reviewer mentions the photos don't do it justice! Katja was out of town when I arrived but made getting the keys easy, and helped me find a US/EU plug converter when I arrived with an almost-dead phone having forgotten mine at home. I enjoyed reading and drinking a coffee on the balcony in my down time. It's beautiful and comfortable.

The location is truly right in the middle--close to Mauerpark and a quick bike ride to many other parks, tons of restaurants and bars nearby, and a 10 minute or less bike ride to Museumsinsel, Alexanderplatz and other touristy places. I am really glad I chose to stay here during my short time in Berlin
