The accommodations were spacious, well lit and comfortable. We loved the amount of dishes and utensils to make our morning breakfast. The Nespresso machine was a nice addition, along with the Nespresso frother.
Its worth noting that this is the 4th storey of the building with each floor having tall ceilings. Be prepared to sweat if you have heavy luggage. The sofa in the communal space was very short, and would be uncomfortable for anyone with poor joints (we travelled with a senior).
The location was different than what we're accustomed to. We had to walk through a building to get to our specific building. There were 2 bus lines about a 5 min walk away however, only one went to Berlin Hbf and wasn't always reliable from a schedule perspective.
Another thing to think about when visiting Germany is that nearly everything is closed on a Sunday. Plan your trip to Germany for Mon-Sat. I've visited Europe multiple times and never been impacted as I had by Sunday closures in Germany. Make it a travel day.
