\\O_O/Given the comments I read from other travellers, the hotel actually has far exceeded my expectation. First of all, there is a U-bahn station right next to the hotel, which takes you only 2 minutes to the central station. The room is spacious, clean and air-conditioned, which is rather rare among other hotels in Germany. It also comes with a large window, which makes the entire room bright and cosy. The front-desk service is 24 hours. The staff are all friendly and helpful.
