Sandra was very helpful messaging before I got there regarding night trains. She was super accommodating when my flight got sent to another airport and I arrived at her place just after 5.30am! Told me to just ring the doorbell and she'd hear me and let me in. Very safe building, as a young (ish) single woman I felt very safe walking to and from the apartment (even at 5am!) and it's about a 5 minute walk from the nearest S Bahn station. Sandra was really lovely and friendly and checked in on me a few times! The room is really lovely and very homely. Bed is super comfy and I had a lovely view of the fireworks from the room on New Year's! Can come and go as you please. Bathroom was great too, bath with overhead shower and nice and cosy! Definitely recommend
