There is a total of 720 units at Camellia Serviced Suites. So, that seems to be neither low nor too high. However, to determine how many units per acre, one would need the land area, which we do no not have. Perhaps you could get in touch with the developer, UOA Group, if you would like to find out. Their contact details are listed here: https://uoa.com.my/property/details/camellia-serviced-suites/

Hope this helps!
