Peter is responsive, and check in/check out process is smooth. It's not super central, but public transport is convenient. It takes less than 20 minutes to Berlin Hbf. Very spacious and private apartment, can hold maximam 6 people. We stay for 3 nights and cook our own breakfast. The equipment and furniture are in good condition,and also very quiet at night. Two shortcomings: it's a top floor flat(5th, UK) without lift, so it's gonna be a bit difficult for people who carry heavy luggage. Also no wifi.
