A Great location: believe me, you will not find the better district to stay in Berlin. Kollwitzplatz looks amazing, absolutely safe, has all possible places to eat and have a coffee (try No Fire No Glory for a coffee and Humami for fusion asian cuisine, for example). Located just 15 mins from the Bundestag and 5 mins from the Alexanderplatz, and is simply Very Nice!
A grate apartment: the unique designers apartment with a soul inside. Shift my understanding how apartment should looks like.
A great hosts: absolutely friendly and supportive hosts. The only thing I'm sorry about is that we haven't spent more time with these great people!
Reccomended to stay in Berlin!
