I didn't see Leona and Gareth much, but they are cheerful, trusting people who welcomed me into their home. The room is spatious, and the location is well situated to explore Kreuzkölln; the nearest S-bahn is a two minute walk away. Communicating with the hosts couldn't have been easier. Remember you're renting a room with shared bathroom, kitchen and shower - wich to me perfectly fits the initial idea of Airbnb.
