Studio, one room or one bedroom: compare the right apartment

Write down the layout, not just the label

For your search, record whether the sleeping area is separate, how many bedrooms you need, and whether the property is an entire apartment. Keep the listing’s original room label as well. Do not translate a one-room apartment into a one-bedroom apartment automatically.

A studio usually describes a combined living and sleeping space, but a source’s one-room category may contain more than studios. If the source does not identify studios separately, a studio median is missing, not equal to the one-room median.

Control the other differences

Compare furnishing, usable floor area, lease length and included bills alongside the layout. A furnished short stay with utilities is not directly comparable to an unfurnished annual lease with separate bills. A low headline price may simply cover less.

Use an area-based estimate honestly

If a compatible source only provides rent per square metre, multiply it by an explicit area assumption. Label the result as an area-based estimate, not a measured median for that layout. Multiplying the median price per square metre by an average area does not generally produce the median apartment rent.
