The location is spot on, and very clean! If you're a walker, it should take you an hour or so to walk towards the "center" of Berlin. Public transportation, around 30 minutes give or take maybe. Neukölln is a rad area, you really felt like you were in a melting pot and I'm glad we had the chance to experience a not so touristy spot. Tata was away so we didn't have the chance to meet her, but her flatmate was spectacular. She went above and beyond to make us feel welcome and we left feeling like friends. She also can give you the lowdown on places to go. Definitely recommend staying here, and if I have the chance to go back someday I will!
