Typically all utilities are grouped somewhere in the cellar, you'll find a water meter room, an electrical meter room and maybe a gas meter room.
1950s to 1970s construction typically grouped the meters on each floor in a hallway closet. Prior to that the meters were installed inside the apartments.
Personally I really prefer having one or a few 25mm2 risers instead of a huge bundle of 5x10mm2 going to each apartment. If they get long enough you'll even have to upsize to 16mm2 or more to account for voltage drop... no thanks.
Pulling 20m 5x10mm2 through 40mm flexible conduit with at least 9 90 degree bends over two floors was one of my worst experiences when I worked for an electrical contractor. We ended up cutting open each conduit to pull on.
