This is the perfect location for those attending the Sydney International Convention Centre as it is about 300m away. For those with wider travel plans the light rail is even closer and easily gets one to Central Station with all its options.
The apartment is in an interesting historic building and has a lot of charm with high ceilings and very generous spaces compared to any of the newer locations. The gym, spa sauna and let pool are good to sue.
The only negative I found was the floor boards, which look great but transmit the noise from the level above very clearly. Hopefully you wont have someone with steel toe caps weighing 120kg!
I would strongly recommend this apartment as a place to stay which offers a sense of a time when spaces were more generous and life was a bit more leisurely.
