Well equipped, super kind host, nice and central neighbourhood. We were staying with friends from overseas whom we wanted to show Berlin. They arrived 2 days ahead of us without speaking any German. Yaz was very very helpful with giving directions and suggestions and meeting every need for the accommodation. I was a little surprised to find the apartment to be "souterrain", i.e. a little below street level (I had imagined something sun lit with view etc.), but out friends actually loved it that way: it wasn't hot, no carrying of heavy bags several flights up, an individual entrance so no disturbing of neighbours when getting home.
