This is my second time in Berlin. The location was perfect, lots of great restaurants close by, little coffee shops and the Penny grocery store is just a 5 minute walk. Having the U bahn just one block away made it extremely easy to get around! Katherine and her husband were extremely responsive and even took care of a issue on our last day. I would highly suggest this place. ohh and the bed was really comfy and the shower had amazing water pressure! It is a safe and secure building you need to go through a locked door from the street, walk-through a courtyard and then up the steps to the flat which also had a very secure locked door.
