The location was great, close to the main train station and right next to a U-Bahn station which was handy. Lots of the sights we went to see were within walking distance.
There was a supermarket near by and plenty of cafes and restaurants, and Naomi recommended some places to eat which was really helpful!
The apartment was lovely, really bright and clean.
The apartment was a great place to explore Berlin from and we would recommend it. :)
