I booked for the Berlin Marathon, by subway, you get to the starting line in 15-20 minutes, with a single line change, pretty easy.
Neighborhood was pretty, quiet and safe, there are stores, cafés, restaurants and a supermarket nearby.
The main door was closed almost every time I had to enter, and it was a little annoying to keep on knocking the doorbell to enter into the building, but I understand the safety measures.
People in reception, always polite.
Elevator is small, and the floors are a little noisy, but it's now bad.
The only thing I'd say to be careful is this: if you have issues with night noises that prevent you from sleeping, be careful, you can listen to all the steps from the people above you (if you're in that room situation), and it's impossible to have a quiet night if you neighbor just keep walking and wandering in its room, it happened to me, and it was pure suffering, bring earplugs.
Also, maybe the rooms need an improvement for the key management, the keyring is extremely heavy and not very practical if you're a tourist, I had to take it off from my keys, to be honest.
Overall, a good place.
