You will have to decide whether the (good, where ?) location out weights the lack of ensuite.
Your resale value can depend on a lot of factors however. The most important one would be the amount of properties for sale in your development. If during the next property boom you decide to sell your apt and nobody else in the development is selling theirs, then it should not matter too much as people won't be as picky, they will just be in a mad rush to get anything.
On the other hand, if there are a good few properties for sale in your development, say for example, they decide to build a prison near or there is no school places for children, or even that they just can't afford them, it may be a bad omen for potential property buyers and will look elsewhere.
