The best cheeseburger in Berlin costs less than 5. Burgermeister is mandatory in town when you're craving for a basic and delicious to the bits chesseburger. 

It is the connection between Leinestrasse u-Bahn and Tempelofer Feld. The park is wild and quiet, and super relaxing :) it is nice to sit on a bench and do some people-watching: it is a big inspiration for illustrators!

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!

Just an amazing cup of cappuccino. Try the Franzbrötchen with it for a basic breakfast. It's a place for someone who appreciates good coffee done with extreme care.

A cute Swedish style breakfast/ cafe place owned by really nice friends, they have a cinnamon bun to coo over, its so sweet and yummy :)
