The hotel is in an excellent location if you're arriving and/or leaving by bus. It's within a kilometer of the ZOB, and all it takes is a straight walk up and down the road to reach the hotel and vice versa. I walked both ways easily with a suitcase of about 15 kg. The city centre is also easily accessible thanks to the Kaiserdamm subway station, and the street with the same name also has plenty of eateries. There is also a fairly large grocery store within a few minutes of the hotel on foot. The entrance of the hotel is built in a strange way though, and you have to draw a big U to reach the reception on foot, as though you were driving.
The front desk girl was quite helpful with places to see, and she lent me a bottle opener for my night beer when she didn't have to. They also sell beer and water at the front desk. The breakfast was more than satisfactory, in fact one of the most memorable hotel breakfasts I've ever had. I'm really surprised to see some people have expressed displeasure about the food in this hotel. I just don't see what's wrong with it.
The hotel is set up with a British theme, which took me by surprise, considering it's Germany. The hallways and the room were clean and quiet. The room was kind of small, but of acceptable size for a single person or a couple on a budget. My only major issue with this hotel is the internet. It worked flawlessly during my first day, but it got messy in the evening on my second day.
