Nena Apartments was a great choice for my stay in Kreuzberg. It was extremely easy to book a room here because there were plenty of rooms available, even for last minute trips like mine. They were responsive online and also had helpful receptionists in their lobby during their open hours. The area was walkable, the building felt secure, and the bed and bathroom were clean. The room had all the amenities listed, but the toaster and the pans were dirty and worn down and the water boiler was unusable due to the grime in its interior that was impossible to scrub off. Other than that, my stay was comfortable and overall felt like home.
