Are condominiums facing south/west more expensive?

That is a widespread misconception that there are no break-ins in the penthouse/top floor. Quite simply because in a multi-family house it is usually not the problem to get into the building. On the ground floor, however, the risk of being discovered is much higher, whereas in the top apartment usually only the resident passes by, and therefore the burglar can generally work undisturbed. By the way, in the past only the servants lived under the roof. The owners lived on the (high) ground floor. I would also pay more for a south-west facing orientation, provided there is no other reason (highway, landfill sites, etc.) against it.

Ground floor is often unpopular due to privacy issues and higher risk of burglary

For family apartments (>90m2) this seems to be changing. Ground floor is quite popular as soon as a garden area is available. For my investment apartments (I once discussed floor plan options here) I already had inquiries about a year before completion, especially because of the approximately 240m2 garden area.

Thank you for the good answers. I bought from a developer and there are a total of 25 apartments in the building. Of all the apartments, I like mine best, along with the one above me and the penthouse apartment above that. Firstly, because of the orientation towards SSW and because it is the corner unit, allowing for more windows and also a more open loggia. The other apartments mostly have windows on only one side. Street noise is not a problem since it is a built-up backyard.

Unfortunately, I could not see the prices of any of the other apartments (except for one). It would also have been interesting to know whether the prices were adjusted, as the land was purchased in 2018 and the construction already began in 2019.

Yes, you are right, the ground floor is now in demand again. Although in the many tight housing markets it is of course difficult to distinguish between demand that is popular and that which is out of necessity. Currently, even attic apartments with slanted ceilings and without balconies can be rented out easily, which 10/15 years ago nobody wanted.

240 m² of garden area, however, is certainly a trump card to play in Corona times.

240m2 garden share for a condominium is downright decadent

By the way, in the past, only the servants lived in the attic. The masters lived on the (high) ground floor.

The masters didn't want to climb stairs either. I believe it's only somewhat fun in a corset. But elevators have solved that problem, so other points count now.
