Karina's apartment was perfect for our stay in Friedrichshain! Great location, clean and comfortable with everything necessary provided. We were met by Ada, Karina's friend, who was punctual, warm and welcoming. Only comment is that there are a lot of stairs and the bathroom is fairly tight (a common feature in these apartments) which might be a issue for anyone with mobility problems. Karina and Ada were great communicators throughout. Thanks for a great stay!
