Gerrit's place is great! I would definetely stay there again if I go back to Berlin. The apartment is bigger than what it seems in the pictures and very confortable. The kitchen has everything you will need to cook, really, you will probably have more things to cook than in your own house. The neighbourhood is quiet and the neighbours are really nice. Gerrit answer all our questions right away everytime we needed information about something of the house.
The place is also really well connected, there's a subway station 3 blocks away that will take you anywhere in Berlin. We satyed there for almost two montn snd we didn't have problems at all.
