Yearn's place in Prenzlauer Berg is perfect. It was clean, well-decorated and warm. We loved having coffee on the balcony at the beginning of our day and a cold beer at the end of the day. The location is amazing. Step out the door and you're in one of the coolest neighborhoods in Berlin--loads of restaurants, bakeries, boutiques and coffee shops. Yearn was a great host. He was available but also gave us our space. He even let us check in an hour early since we accidentally took a morning train in from Hamburg. Highly recommend this place.
