Exceptional

Liked: It was a very great and pleasant experience. The location is not bad as it is really close to the S-bahn station as well as the train station (line 11). The environment was quiet and restaurants and shopping were very convenient. But generally, it is great.
Disliked: The only problem is the wooden part of the bed. And I hit my head a couple of times. when I was lying down for sleep.

It was OK, good room...

Liked: Near the place I had to be for work. No far from the HBF with S-Bahn. But the location is not particularly great.
Disliked: No warm water for the shower I had only a free breakfast for this. I would have apperciated a good discount on the room too. Breakfast below average, no water, no sparkling water, just coffee and orange juice.
