First, the location is fantastic. Only 5 mins west of the Sophia-Charlotten Plaza subway train station (Line U2). I arrived at Berlin in the midnight due to the delay of train, but there was no problem for me to find the location and check in by myself. It is also very close to the former royal palace- Charlottenburg, less than half an hour by walk. The host is very friendly and responses very promptly for any problem during the check-in. The room is accurate as described, very easy-going style, and total enough for a traveler to stay for a weekend in Berlin. The water heaters in room is also very powerful. Together with soft bed mattress and quilt, I really enjoyed my three-night sleeps. For any travelers with a limited budget, highly recommend! You will never regret!
