The Adelaide Marriott Hotel opened in August 2024 inside the city's historic General Post Office building, becoming South Australia's first Marriott-branded hotel. The AU$200 million project pairs 285 rooms with three dining venues inside a heritage-listed shell restored by Adelaide architects Baukultur.

Entry rate From AUD 210 Learn more → The place The hotel occupies Adelaide's General Post Office (GPO), a heritage-listed landmark more than 150 years old on the corner of King William and Franklin Streets, facing Victoria Square in the heart of the CBD.
The concept The AU$200 million redevelopment, led by Adelaide architecture firm Baukultur, threads a 14-storey tower through and above the heritage GPO shell, pairing original stone facades and postal-era details with 285 contemporary guestrooms and suites, including a Presidential Suite and a 24/7 Club Lounge on the executive floors. It is South Australia's first Marriott-branded property and one of the anchor projects in a wider AU$1.2 billion wave of hotel investment reshaping Adelaide's CBD.
The project's selling point is less about novelty of form than about reviving a building Adelaide residents already knew and cared about, giving the hotel a civic weight that new-build towers on the same streets don't have.
Dining & wellness Dining runs across three venues: the Greatroom at the hotel's heart, Penny Blue for modern Australian plates in a heritage-nostalgic room, and Exchange Lane, a laneway bar that shifts from morning coffee to evening cocktails. Guests also have an 18-metre indoor pool, a fitness studio, and more than 760 square metres of event space including a 295 sqm ballroom.
Our take Repurposing a beloved civic landmark rather than building from scratch gives the Marriott a sense of place few new-build hotels in the CBD can match; the trade-off is a room count large enough that some of that heritage intimacy gets diluted by convention-hotel scale.

Beautiful hardware, but nickel-and-diming ruins the Marriott experience
This stay felt more like a transactional business hub than a premium hotel.
The Good: The lobby is grand, and the Club Lounge is beautifully designed. Breakfast was enjoyable, largely thanks to the Indian lady at the breakfast reception, she is exceptional and by far the best staff member on-site. The pool was also quiet and relaxing.
The Bad (Where it falls apart):
Room Service: The service was poor, but the real kicker was the pricing. Charging an additional delivery fee of nearly 20% is excessive. At these price points, ordering room service shouldn't feel like ordering from a budget app like Grab or Uber. It completely cheapens the guest experience, they are also charging you extra 2% for using a card but the funny thing is when I wanted to give cash as a deposit on check-in and separately pre-pay the room charges with a card, instead if the $100/ per day deposir, the receptionist mentioned it has to be $200/day. I just find this very two star standard and insulting for a Marriott Elite member and lifetime member.
Lounge Food: The lounge itself looks great, but the culinary offerings are underwhelming and need a major upgrade.
Conclusion:
If you aren’t a loyalty member utilizing lounge access to offset the extra costs, this hotel simply isn't worth it. It lacks the warmth and elite experience @MarriottBonvoy usually guarantees. I will be choosing a different property for sure on my next visit.

Had an amazing one week here. The location is fantastic and the room is spacious. When we first arrived in front of the hotel, a staff member quickly ran out to help with our luggage, such a thoughtful touch. Every time we went out and returned, the staffs we met greeted us warmly and were always friendly. One morning around 6am, I needed an item that the hotel didn’t have, and the staff over the phone kindly offered to buy and deliver to my room. Tho we declined his help, ended up leaving in a hurry, I really appreciated the thoughtfulness! Will definitely book again.
We loved every part of our stay at the Marriott Adelaide. From the moment we entered the lobby, the hotel felt modern, luxurious, and very well designed. The common areas were beautiful, with a high-end atmosphere that made a great first impression and continued throughout the entire property.
Our room was just as impressive. It was comfortable, clean, spacious, and thoughtfully designed, with quality finishes and everything we needed for an enjoyable stay. The attention to detail throughout the room made it feel more special than a typical city hotel. It was a great place to relax after spending the day exploring Adelaide.
The location in the city center was also very convenient and made it easy to get around. Even though the hotel is in the middle of the city, the atmosphere inside still felt calm and relaxing. The lobby and other shared spaces were places we actually enjoyed spending time in rather than simply passing through.
The staff were friendly, professional, and welcoming throughout our stay. Everything about the experience felt organized and polished, which matched the high-end design of the hotel.
Overall, the Marriott Adelaide exceeded our expectations. We genuinely loved everything from the room to the beautiful lobby and overall atmosphere. It is a very well-designed, upscale hotel that feels luxurious without being uncomfortable or overly formal. We would absolutely stay here again and highly recommend it to anyone looking for a high-end hotel in the center of Adelaide.
The Marriott Adelaide is a wonderful, new property in Central Adelaide that is convenient for walking to dining and shopping, like Rundle Mall and Adelaide Central Market. The hotel has exceptionally clean rooms and friendly staff at all interactions. Valet parking was fast and convenient.
We stayed in a family suite, which was a double-bedded room and a king-bedded room through a common entrance. This provided great space with kids, but do note that all rooms in this class have a roll-in shower rather than a standard shower in the bathroom on the king-bed side. As a Bonvoy Ambassador, access was available to the nice executive lounge.
I will certainly return again when in Adelaide.
We had an absolutely wonderful stay at the Adelaide Marriott. From the moment we arrived, the service was impeccable. Every staff member was friendly, professional, and genuinely focused on making our stay exceptional.
The hotel itself is spotless and beautifully maintained. Our room was amazing, comfortable, modern, and thoughtfully designed with every detail in mind. The breakfast was also outstanding, with a delicious selection of fresh, high-quality options each morning.
The combination of exceptional service, beautiful accommodations, and attention to detail made this one of the best hotel experiences we've had. We would not hesitate to stay here again and highly recommend it to anyone visiting Adelaide.
