There's nothing more revigorating during the dark winter days than spending a couple of hours in a sauna. Germans have mastered the art of sauna and you can find amazing pieces of architecture in the public swimming pools (Stadtbad). I find Stadtbad Neukölln very peculiar in its neoclassic architecture and it's definitely a wallet-friendly option to enjoy some sauna time there. Be prepared to be naked in front of man and woman!

New type of museum. It's a private collection from contemporary art pieces such as by Anish Kapoor or Nobuyoshi Araki to Chinese imperial furnitures or ancient Asian sculptures. The collection is wonderful and the light design is perfect. There is no description or title of the artworks - it invites you to purely see/feel the artworks themselves without influencing by the names. Must to go.

Osteria Sippi is an incredible simple italian restaurant where everyone feels immediately at home. They not only know their food game but have also an impressive range of really good wines.   

It's a small bookshop to be stuck forever. Here you can find the most beautiful collection of art/photography/architecture/fashion/food books and magazines, not to count it's just a walk distance to diverse galleries around the neighborhood.

Located in a vintage ballroom, Clärchens Ballhaus is a nice lunch destination. Try the "Käsespätzle" with applesauce!
