What is the value of an aggregated price per room across all apartment sizes? A 1 room apartment is going to cost more than half of a 2 room apartment, which is going to cost more than one third of a 3 room apartment.
The price per room seems like it would be more useful if it was shown as "price per room for 1bdrm" and able to be switched to 2bdrm or 3bdrm and so on.
