Hardly getting over it.
Among other things, not managing the almost inevitable problems you'd get if a couple of flats in a residential block are continually rented out for a few nights at a time to (for example) stag night groups - noise at very unsociable hours.
Also, if you're sharing a flat with a few friends for just a few nights, you don't often notice or complain that repairs or structural improvements need doing, while long term tenants would be more likely to complain about low water pressure, noisy pipes, or even request a rent reduction for a family sized flat on the 5th floor without a lift.
It doesn't help that rent in Berlin is very low (even now) compared to Paris or London, so holidaymakers are less likely to raise an eyebrow if a landlord decides to charge the top end of reasonable for renting an apartment. Again, not good news for local longterm tenants.
^^^^This.
Unfortunately, German landlords (especially the small ones, which is the majority) are not yet wise to enforcing "no stag/hen groups" rules etc, and the other, longer-term residents, end up bearing the brunt of the nuisance that causes, as well as the rising rental prices.
