We had a great time at Tomos and Mirko's place! It was a quick and easy trip from Tegel airport following Tomos' directions (~30-40 mins), and Tomos was easy to coordinate with around our very late flight. The location of the apartment is great. Neukölln has the best food, great bars, and has easy access to the rest of the city. We rented bikes at a local shop (4 euros/day!!and ) and used Tomos & Mirko's map/recommendations to find the yummiest food, swim in two beautiful lakes, and hang out and relax in parks all over the city. The room is bright, airy, and very clean, and the apartment looks even better in person. All around a great weekend, and I highly recommend their place.
