Ich bin vor 6 Monaten in eine neue Wohnung gezogen, alles war in Ordnung, bis es anfing kalt zu werden, jetzt habe ich überall in der Wohnung Schimmelflecken. Ich lüfte meine Wohnung zweimal am Tag, mehr kann ich nicht tun, weil ich von zu Hause aus arbeite und es draußen sehr kalt ist und meine Heizung ständig auf 2 läuft. Wie kann ich damit umgehen? Sollte es ausreichen, die Form von Zeit zu Zeit zu reinigen, oder brauche ich spezielle Dinge? Soll ich es dem Vermieter sagen?

Lüftung! Open all windows, 5-10min. Air should completely replace. And after maintain 18degrees.
You have to open your windows more often
Employ something called „stoßlüften“, basically fully open your windows for 5 minutes, then close them again. Your stuff in the apartment and the walls/floors/ceilings will stay warm, just the air needs to reheat. Do that 3-4 times during your workhours and you are gonna be totally fine.
The only solution here without doing something structural to your home: vent more. See if you can leave a window on a tiny crack or something. If this forms within a couple of hours then this is A LOT of condensation. Do you shower a lot? Or constantly making tea?
Black mold is best cleaned with some chlorine solution. Please be aware black mold is very bad for your health. Read up on how to avoid and clean it.
You should contact your landlord about it, you are obliged to do so under the Mietrecht. It might also be the case the landlord is responsible to solve this issue if it is a purely structural thing (or bad ventilation possibilities). However, if you don’t vent enough and don’t heat the apartment sufficiently than it might be on you. I cannot judge that from here.
Keep in mind that houses in Germany are built for the winter and not for easy reconstruction after natural catastrophies. Germans do not have ventilation systems built into the walls or ceilings so it is up to you to ventilate. I saw that in USA people tend to keep the windows closed and regulate humidity and temperature with a central device. Germans prefer heat radiators and open windows for control of heat and humidity.
Your landlord would say you’re breathing way too much.
I suggest you get yourself some hygrometers too, easier to monitor the humidity that way.
The heater [set to 2](https://en.wikipedia.org/wiki/Thermostatic_radiator_valve#Temperature_scales) means 16 degrees (or 17 on Danfoss), that seems a bit too cold. Crank it up a bit and ventilate more.
Get a thermometer with hygrometer and monitor the humidity.
If the windows are single-pane, you’re basically out of luck, but if they are not, you should be able to keep them dry.
People think it’s the cold that would make them sick but in reality it’s lack of ventilation.
Open your windows more often and consider getting a dehumidifier
Clean your mold often, its not healthy for your respiratory system. Clean it with vinegar. Wipe of the water from the windows. Dehumidifier.
It’s not just ventilation. The temperature inside could also be too cold.
Additionally to ventilate your room more frequently you may get an electric dehumidifier. But don’t get one for 20 euros on Amazon. One that actually works (has enough power) will probably cost about 200 euros.
In addition to what people has said about proper ventilation and increasing the heaters temp (3 would be better), cross ventilation helps a lot. That means completely opening all windows for a few minutes so that a stream of air can flow through the apartment. Of course that means leaving room doors open. Doing that twice a day should be enough. Also male sure that if you have furniture or closets next to any of the walls facing the outside you have to leave certain gap between the furniture and the wall, at least 20 cm or so. If you have the option to place the furniture somewhere else other than these walls then that’s a better alternative.
If you still see the condensation after doing all this then there’s a problem with the apartment itself and that needs to be fixed by the landlord.
The problem with mold doesn’t appear suddenly, so you might already be having this problem for a few weeks.
