Hotel that is well situated and clean, plus has great views looking out over the city on one side and the Tiergarten on the other. The downsides - I had the housekeeping service knock on my door at 0750 in the morning (!?), plus there is a lack of lifts. There are only 3, and all of them very small, meaning if you are staying on the upper floors it is a chore getting to and from your room.
