The Marina Apartments provide quality of living and sits adjacent to the complex amenities that includes swimming pools, local bar, restaurants, malls, beaches and championship golf course. So, choosing this area for living would definitely be a good idea.
You can also consider contacting few agents via "Agents" section, they can suggest you other properties to invest in your desired location. Deciding on renting vs purchasing an apartment totally depends on your budget.
I believe its a good buy and rental return is pretty decent too. Could you please let us know what is the purpose of investment. Is it a pure investment or more of a holiday home?
The reason I asked the question was because if you were purely thinking in investment terms, then there would have been many different options available out there.
Since you are planning to live there yourself, then its more of a matter of personnel choice and hence the investment is feasible and sound.
I am not an agent, however I have very good know how of the market, primarily through investing and social circle.
