This is a delayed review from our stay in July, but it definitely deserves the praise. We loved the hospitality. The staff were friendly and welcoming, and the room was very clean, comfortable, and spacious. We stayed as three female travellers and felt comfortable throughout the stay. The beds were big and very comfortable, which made a big difference. Parking is available, though the car park entrance is on the side, so we had to circle once or twice to find it. There were also a few stairs to carry luggage before reaching the lift, which is just something to be aware of if you have heavy bags. The gym was great, especially the nice view from the top floor. A really pleasant bonus. Overall, a very enjoyable stay and one that’s worth recommending, even months later.

We received a very warm welcome from the staff, and the room initially looked good when we arrived. As we were heading straight out for an event, we didn’t spend much time in the room at first. However, when we returned later, we noticed that the towels were not clean, the bathroom was dirty, the TV was not working, and the Wi-Fi was also unavailable. We contacted reception to request fresh towels and to report the issues with the TV and Wi-Fi. Fresh towels were provided, however the TV and Wi-Fi issues were not resolved. When hanging the towel up, the entire towel rack came away from the wall, which was quite disappointing and felt avoidable. The following morning, when we went down to breakfast, I turned around and left almost immediately as it was evident that the dishes at the buffet were not clean. By that point, my confidence in the overall cleanliness of the hotel had been lost. I would like to note that the staff were consistently apologetic, polite, and pleasant throughout our stay. However, I do feel that the hotel has the potential to be much better, and with improved cleanliness and maintenance standards, the overall guest experience would significantly improve.

My partner and I stayed three nights in an upper level deluxe room with harbour view. We especially enjoyed the view looking over the parkland areas with the Harbour Bridge and Opera House in the background. We also especially appreciated having two comfortable lounge chairs that could easily be turned to face either the view or, at night, back towards the room. We also enjoyed the included breakfasts, especially the choice of some vegetarian Indian and Chinese cuisine options, which added to the interest of these breakfasts. Being able to park our car in the basement area for a reasonable additional fee was also good in this location quite close to central Sydney.

Room was very continently located with comfortable beds. The air conditioner was great during the day but over night seemed to be non existent and room became very hot & we had no control over the temperature.
