When I`m traveling myself I`m renting my room. It`s part of a two bedroom shared flat in the great center of Berlin Prenzlauer Berg.
The tube station is just 3 minutes away, the metro tram right infront of the house. There are snack spots, restaurants & supermarkets all over the Kastanienallee.
I`ve got a flatmate living with me. If I cant give you the key & a warm welcome directly, he`s always happy to help.
You shouldn`t be allergic to dog hair, cause I`ve got a dog living with me. :)
