Excellent in all ways. The host could not have been nicer, more responsive or more helpful. The place was excellent--very well equipped, with thoughtful "touches" both in kitchen supplies and decorations. They even left an adaptor plug and lots of maps! The beds were super comfortable. And it was surprisingly quiet for being in such a central place. Quick walk to the underground. Lots of great cafes and walks near the flat. We loved being in a more diverse and "artsy" part of Berlin. 5 stars.
