We absolutely loved this apartment. Great location - only ~250m from the U-Bahn station, and from there it is only a 5 minute journey to Friedrichstraße. The neighbourhood is lovely too and you can just walk around and take in the environment and atmosphere.
The size of the apartment was great for two people, and the wee kitchen was perfect for cooking. Beautiful building too.
Naomi is also a wonderful host, and helped us whenever we had a question; I highly recommend staying here!
