ᐅ Centralized or decentralized ventilation system

Hello everyone,
Maybe you can help me.

We have a small apartment of about 35 to 40 square meters (375 to 430 square feet) with one bathroom, one master bedroom, one living area, and one storage room.
From around mid-October to about April, there is recurring unpleasant musty basement-like odor in the apartment.
The apartment is not used daily, so ventilation is irregular.
There is no mold or anything similar present.
I have been thinking about either a decentralized or centralized ventilation system. I understand that with a centralized system all rooms would be ventilated.

Would this solve the problem, and are there ventilation systems available that fit this size? So far, I have only found larger units. Or is it possible to adjust them down to a size that would be suitable?

That is too low…

An apartment in the basement?

Please explain the situation in more detail first. Also about the house and the location of the apartment.

I don’t quite understand this.
Auto-correct on my phone. It was supposed to say “and the doors…”

The apartment is not in the basement; it is a storage room—I misspoke.

But 19 degrees less is too little. In our apartment, we have a maximum of 20 degrees Celsius (68°F), and that already feels too warm for us.
