I would definitely recommend staying in TinTin's apartment on a trip to Sydney.
We were travelling with our toddler daughter and sister and it worked out cheaper to stay here than two rooms in a budget hotel...and it was so much nicer! It was great being so close to most things and having the ability to sort our own food if needed and relax in the lounge watching films once our daughter was asleep using the projector. Having a washing machine and dryer was also really helpful when a toddler can get clothes dirty so quickly.
TinTin was excellent at responding to communication quickly and ensuring that everything was ok with our stay.
We went upstairs to look at the pool and the view was amazing - we wished we could have gone in it but unfortunately we weren't staying many days and the weather wasn't really good enough for us to use it. I'm sure it would be fantastic on a hot summer day.
