I stayed here for 2 nights and was impressed with the service. The staff is extremely responsive and attentive to your needs. Bell staff was readily available upon check-in and check-out to collect bags. Check-in process was extremely easy and quick, and we even got a room upgrade and was able to get our room in the morning - hours before normal check-in time.
The concierge desk is also very helpful and provided excellent dinner recommendations and secured reservations for us.
The location of the hotel is within walking distance to some of the best tourist sites: Sydney Opera House, Royal Botanic Gardens, the Rocks, Art Gallery of NSW. It is also very close to Circular Quay, which allows for easy public transportation to points beyond the city center (e.g. Manly Beach, Bondi Beach). I would definitely recommend this hotel!!
