Good morning everyone,
I have been living in my own home since June (maisonette apartment, 3 rooms, 70m2 (750 sq ft)). Although I ventilate frequently and wipe off the window condensation twice daily (I have already experienced this with fogged windows in my previous rental apartment, which was also newly built), the windows still fog up from the inside, especially at temperatures below 5°C (41°F).
The two Velux windows (kitchen, dressing room) are particularly affected. This morning, while cleaning, I noticed the first black "spots."
Is this already mold or just dirt that, combined with the condensation, looks like mold?
I look forward to your answers.

I am aware of that. However, it can’t be normal for such high humidity to exist in a new build. Therefore, I suspect it’s a temporary issue simply caused by moving in 6 months ago, and it should improve after the first year.
In my previous (rented) apartment, I had the same problem despite ventilating several times a day.
Renting a dehumidifier is unfortunately not cheap either; currently, I see about €7/day, which is nearly €210 per month! You don’t actually rent the dehumidifier, but rather buy it on eBay or from classified ads (it can, of course, be secondhand) and then sell it again a few weeks later. With a bit of luck, the drying costs will only be electricity and a small amount of pocket money.
By the way, this applies to many machines that you only need temporarily in the house 😉 (at least more than just an afternoon).

Can I set up the device in my hallway, keep the doors to the other rooms open, and dehumidify centrally from one location? Or would it be better to dehumidify one room each day (living room, bathroom, bedroom)? I don’t want to buy several devices at the start. I have placed a hygrometer in each room in the basement, and when the reading approaches 70% humidity, I move the device to that specific room. If all readings stay below 65%, I simply put the device in the room with the highest humidity and leave the doors open. You have to try what works best.
In your apartment, you will likely have lower humidity levels than I do in my nearly unheated basement. Upstairs in the living areas, I currently have about 45-55% depending on the weather. My home is an older building, but the screed in the bathroom and toilet was recently redone. In those rooms, I don’t need a dehumidifier.
