I am a solo female traveller and found this place to be supurb. Everything was immaculately clean. The rooms were spacious, modern and well lit. for those who want to be social, there are plenty of lovely common areas. I especially appreciated the bright atrium in the lobby. This is a lobby is actuall a great place to work* or socialize.
*The wifi was fairly choppy for me. However, this is so often the case in Germany, so I won't hold it against this establishment.
Don't hesitate, book this place already!
