The Zoo and the Aquarium is on the things that never changed during the years. Everytime I visit it looks exactly the way when I first went when I was a little child. This place gives me a lot of inspiration, I like the way they want to make the cage enviroment look natural with artificiel light.
Berlin has plenty of magic cafés in every corner. This is one of them. It's quiet and it has a mixture of lights and furniture that really catches me. Cakes and coffees are also very tasty.
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!
The typical Berlin winter is biting cold and grey. In combination with the hardness of the city and the angry natives, it feels like a hostile area. Why it's worth experiencing it? Because that's the way this city is.
