Absolutely loved the stay! Usha welcomed us very warmly, even when we arrived terribly late because of delays. The neighbourhood is nice and quiet, by bike you can easily reach the centre and other parts of Berlin. The house and its interior is beautiful, Usha and her partner are both musicians so there's a piano room as well. She was very friendly and communicative and cat Luna is also wandering around. Would definitely recommend their place, it's a perfect base to explore Berlin :)
