It's an indoor market, which makes it a great option in winter if you are looking for anything from kitsch to classy. I like it because you find lots of old objects that transport you to the past.
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.
The Tempelhof Airport is now closed and they have transformed the landing field into a public park area. As soon as you go there you notice that usually you don't get to see that much sky in the city so entering this area for the first time is quite overwhelming. I especially love the old softball fields that have been built during the American occupation.
A very nice little second-hand bookstore, including a shelve with international books in French, English, and Spanish too. Always nice people to meet and a great selection of art and cook books, for affordable prices.
