If you want the data without getting the InfoWindow HTML showing at all, you simply have to re-work the prototype of google.maps.InfoWindow:

google.maps.InfoWindow.prototype.open = function () {
  return this; //prevent InfoWindow to appear
}
google.maps.InfoWindow.prototype.setContent = function (content) {
  if (content.querySelector) {
    var addressHTML = content.querySelector('.address');
    var address = addressHTML.innerHTML.replace(/<[^>]*>/g, ' ').trim();
    var link = content.querySelector('a').getAttribute('href');
    var payload = {
      header: 'event',
      eventName: 'place_picked',
      data: {
        name: content.querySelector('.title').innerHTML.trim(),
        address: address,
        link: link
      }
    };
    console.log('emit your event/call your function', payload);
  }
};
