I'll start by simply saying the apartment is perfect. It is absolutely as described, clean, beautiful and equipped with everything needed for a good trip.

The location is also great - within a five minute walk you're at the S-Bahn station, and from there a five minute ride to Potsdamer Platz, seven minutes to Brandenburger Tor, Unter den Linden and Friedrichstraße. You also have two bus lines from the corner of the street (less then 1 minute walk) to the west - KuDam, KaDeWe, the Zoo.

You have several nice supermarkets nearby, including organic ones, and everything you might need in the nearby Hauptstraße.

Other nice things in the area - several very good and nice Coffee places just around the corner in Leberstraße, and in Akazienstraße.

Finally, Gerhard is simply an amazing guy. He helped me so much during my time in Berlin, with everything.

In conclusion - You will have a great time here in the apartment (and in Berlin of course), and the most wonderful host possible.
