Stayed here for 4 nights recently. Had stayed at the Meriton in Kent St a couple of years ago and were very spoilt, having a room with a great view. At Meriton Pitt St it didn't quite have the same view, but the high standard of Meriton aparments was still evident.
We attended the Paris Opera Ballet at Capitol Theatre which was a short 10 minute stroll. Very convenient. The location of this apartment is close to Town Hall station and the QV building. Lots of good little sushi places close by.
I prefer to stay in an apartment as opposed to a hotel, mainly due to the space in the rooms and the affordability.
Would definitely consider Meriton when I next visit Sydney.
