Had a great time in Berlin, also very much due to this great apartment. Spacious, fully equipped and super neat. Neukölln is great, everything you need is there. Not that I cooked because the surrounding streets are full of cheap but very good restaurants. But if you want to check out other districts, the U-Bahn is literally under 1 min. walking, so location wise you'll be hard pressed to find a better choice. O yeah and the coffee of Leuchtstoff is seriously amazing and exactly in the middle of your 30 sec. walk to the U ;)
