Natalie's apartment was very clean and had all of the amenities you need for your stay in Berlin. She was very responsive. When I had a small issue she came over quickly to resolve which was so helpful. It is 1 block from the S train which is so convenient. There are 2 grocery stores right as you exit the train to pick up all that is needed. The neighborhood is cute and we walked to Mauer park one day and passed a ton of cafes and shops. Suggestion: we took a cab from the Hbf which ran about 17 Euros but was easier than the 3 trains you need to return back to Hbf (for 2 of us that was 7 Euros).
