Fukien trees are tropical trees, so they can take the heat in stride. If you have a partly shaded area on your balcony, that would probably be perfect. It can take a fair amount of sun, but you'll probably need to acclimatize it to your conditions. There are very few trees that do well inside, ficus is one example. Fukien's are pretty finicky plants to begin with, giving them indoor conditions will just make it all the harder to keep healthy.
