I spent a month in this apartment and had a really great time. The location is amazing, right next to the S-bahn and U-bahn station, only a 10 minute walk to Alexanderplatz, with a great view over the city including the Fernsehturm. I could spend hours just watching this view with the trains passing by.
Everything was very clean and all the necessary things were available. Due to corona we couldn't hand over the keys in person, but the communication was very fast and easy, so it was not a problem.
Highly recommended - I hope to be able to come back soon!
