I had a nice stay in the apartment! It was clean and check-in process was smooth. Jonathan has recommendations about places to eat and visit.
Apartment doesn't get direct sun in it. I consider this a plus as it doesn't get hot inside (Berlin could be quite hot).
Kitchen has plenty of things, so it is easy to cook your own meal. It also has nespresso machine. One minor thing which I missed was 0.5 l beer glass. All the glasses that I could find were 0.4 or smaller.
There is an Alexa speaker in every room, so one could listen to music.
