Stayed here for 3 nights over New years eve. The rooms are of a good standard with all the facilities you need. The hotel is located about 10 mins walk to central tube station and takes about 10 minutes and costs between $10 - $15 in a taxi to get to the rocks/opera house area. The staff are what made our stay though they were all very helpful with anything we wanted. Only negatives were that gym and pool were both out of action during our stay and the area that the hotel is in is very quiet with not much going on. Would recommend though if you are looking for somewhere to stay in Sydney.
TIP: It was cheaper to get a Taxi to the airport from the hotel than it was to catch the train to central and walk to the hotel - would imagine this depends on what time of day you are travelling though.
