I stayed at the Canvas apartments for five nights. The apartment was very easy to find and the communication was great. The free parking was also very convenient.
There were only a few negatives. The most obvious was that it is really noisy - given the location (which is directly in front of the train lines and the fact that all of the windows are sightly locked open), I was shocked at how noisy it was and was woken up several times each night. The shower was also broken and you had to hold it in your hand in order to use it. The only other negative was that the WIFI is virtually non-existent. I was unable to work from the apartment and ended up using a remote wifi dongle from telstra.
If you are looking for a very central location and noise doesn't bother you, then this would be a great find.
