We had a FANTASTIC experience at Peter and Andreas' apartments - they were just perfect for a large group. The beds and bedding were very comfortable, everything impeccably clean and easy to use. The communal space was brilliant and made our stay in Berlin ideal. There was even a little Christmas market in the courtyard...very special memories. Peter and Andreas could not have been more helpful to us, answering all our queries instantly and accommodating our various requests very happily. I will definitely return here - and cannot recommend more highly for a large group of people who want their own spaces but also have the facility to get together in one perfect space. The location was easy for public transport too - and the district great; shops, cafes and restaurants plenty!
