If you only need the "PostalCode", you could use JsonParser instead of having a bunch of classes:

JsonParser jsonParser = new JsonParser();
JsonObject address = jsonParser.parse(json)
    .getAsJsonObject().get("Response")
    .getAsJsonObject().getAsJsonArray("View").get(0)
    .getAsJsonObject().getAsJsonArray("Result").get(0)
    .getAsJsonObject().get("Location")
    .getAsJsonObject().getAsJsonObject("Address");
String postalCode = address.get("PostalCode").getAsString();

or for all results:

JsonArray results = jsonParser.parse(json)
        .getAsJsonObject().get("Response")
        .getAsJsonObject().getAsJsonArray("View").get(0)
        .getAsJsonObject().getAsJsonArray("Result");
for (JsonElement result : results) {
    JsonObject address = result.getAsJsonObject().get("Location").getAsJsonObject().getAsJsonObject("Address");
    String postalCode = address.get("PostalCode").getAsString();
    System.out.println(postalCode);
}
