Tomos and Mirko are great host. It was pleasant to spend some days in their appartment. The room was clean and the bed confortable, perfect to spend some days in Berlin.
The location is perfect, very close to the U7 in Neukölln, the U8 in Hermanstrassrand the ring in both station. You can easily access to the whole city in just a few minutes.
Tomos and Mirko have also good advice to visit the city and to eat or hang out at night.
