That site is just a marketing and database site. All reports on saunas, HGs, etc. will be found on the Macau section of this forum or the relevant section on the Chinese forum.
If you want to try a Macau HG, you will need to make a call to see if the girl is available. If yes, then the papasan/mamasan will give you instructions on the hotel. Once you get to the hotel, you call the papasan/mamasam again to get the room number. Then go to hotel room, have your fun, pay the girl and hopefully you will write a report to share the details
