Determining the Place according to latitude and longitude

问题

I'm using google maps API to determine a building(Place) which is a Google Point of interest. I'm trying to get the place reference for future use. but due to API limitation or whatever limitation. I can't get the exact place. As an example below latitude longitude belongs to "The university of Sydney". Using this code I could derive University of Sydney but as second result and also I tried many lat long but sometime appropriate result comes in the end or first. These places are prominent to Google Places Search system. The radius of this request looks lame to me. Is there any way to retrieve the exact place ?

  var pyrmont = new google.maps.LatLng(-33.88858402464521, 151.18735671043396);    
  map = new google.maps.Map(document.getElementById('map-canvas'), {
    center: pyrmont,
    zoom: 15
  });

  var request = {
    location: pyrmont,
    radius: 1,
  };
  infowindow = new google.maps.InfoWindow();
  var service = new google.maps.places.PlacesService(map);
  service.nearbySearch(request, callback);
}

Advanced Thanks
