Jonathan and Matilde are wonderful hosts and I highly recommend their place for a stay in Berlin. The apartment is very well-kept and filled with unique features (mostly built/added by the hosts), and the location is excellent in terms of both nearby activities in Prenzlauer Berg + access to public transit. The two cats, Ringo & Yoko, who live there are adorable and great company as well. The bedroom is the perfect size for one person, and can comfortably fit a couple if you don't mind sleeping close.
If you prefer to stay in an Airbnb that is actually a home, with two hosts who actively live there, then reach out to Jonathan & Matilde! Ask them about their work and the artist community in Berlin. Don't hesitate to ask them for recommendations on anything - their input will enrich your experience here if you are open to it.
