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!
As its name suggests this bibliophile cabinet accommodates finds from many centuries and areas. Everything - junk and treasures - from the floor up to the ceiling. Don’t be shy to ask the owner if you’re looking for something specific.
ABC is Berlin´s Eggs Benedict Mecca. This laid-back, fun little shop will provide you with one of the city´s best Aussie brunches - provided you reserve or are willing to wait for some time. But the eggs, the coffee and the Bloody Mary really make it worth.
A good place to drown your Berliner winter-melancholy. The bartenders are top notch and the interior is warm but stylish, with the inevitable retro vibe. Open from 6 till late. There´s also a legendary (and kinda expensive) restaurant next door, which provides the bar with some excellent snacks. Works for dates and for friends, but if you´re planning for a bigger group it might be wise to reserve.
A very close friend of mine owns this bar. It looks tiny from the outside, but it has two rooms you have to pass until you get to last one which is a discofloor. I play music there from time to time and I am always surrounded by nice people und friends.
