Comparing two units in francs per square metre says nothing until expected turnover enters the equation. An expensive unit on a busy street may represent a lower ratio than a cheap unit with no passing trade.
The acceptable ratio depends on the activity's gross margin: a low-margin activity bears only a low ratio. The prudent rule is to compute it on the low turnover scenario, not on the hoped-for one: a rent that is only bearable in the best case is a rent that is too high.
