Practical details
Why it's worth checking out
Adelaide Marriott Hotel places guests in the Adelaide CBD, within the historic General Post Office building and overlooking Victoria Square. Its central position makes it a practical base for exploring the city, with Adelaide Oval, Rundle Mall, Central Market and Her Majesty’s Theatre all within walking distance. Adelaide Airport is also described as being around a 15-minute drive away, while the nearby convention centre makes the hotel suitable for business stays as well as city breaks.
Accommodation ranges from Superior, Deluxe and Premium rooms to M Club rooms and the Clock Tower Suite. The hotel also has a 24-hour fitness centre and an 18-metre indoor pool, giving guests options for exercise and downtime without leaving the property. M Club access is available to eligible Marriott Bonvoy members and guests staying in selected rooms or suites. The lounge is reserved for guests aged 18 and over and includes food and drink provisions such as a hot buffet, snacks, coffee and tea, desserts, hors d’oeuvres, non-alcoholic drinks, beer and wine, subject to the access arrangements outlined by the hotel.
Dining is spread across three outlets. Penny Blue is the signature restaurant, presenting contemporary dining in Adelaide CBD with a Modern Australian focus and an atmosphere that combines polished design with references to the past. Exchange Lane takes a more casual, flexible approach, operating as a café-bar with lane access and outdoor seating. The venue is presented as a place that moves from morning coffee through to evening drinks, with all-day dining and takeaway available. Together, the options cover a range of stays, from a quick coffee or relaxed meal to a more considered dinner on site.
The building’s history is central to the hotel’s identity. The interiors draw on the former GPO’s links with telegraphy, stamp printing, postal services and meteorology, with historic photographs, contemporary work by local artists and a First Nations Welcome forming part of a curated collection. QR codes throughout the hotel allow guests to explore more of that story. With meeting and event spaces designed for conferences, meetings and social occasions, the Adelaide Marriott suits travellers wanting a full-service city hotel, couples looking for an urban stay with dining on site, solo visitors seeking a well-connected base, and groups attending events in the CBD.
