Oversettelse - Kinesisk med forenklet-Engelsk - 青岛市东海西路37号C栋6层E室

E室= room E，
6层= Floor 6，以次避免英美的楼层异议。

--translation of lij899's comments--
E室 should be translated as "room E" instead of "unit E"

6层 should be translated as "Floor 6" instead of "6th Floor" to avoid ambiguity arising from BrE and AmB differences.
--end of translation of lij899's comments--

Flat E, 6th Floor, Block C
