We stayed at Sam's place for 8 nights.
Unfortunately we didnt get to know to Sam because he wasnt in Australia but his mum Helen did a great job and was super nice.
The bus station is about 2 minutes from the condo and u will be in the city (Central Station) in about 10-15 minutes.
The coffee shop close to the condo is also very good.
The only thing I can suggest is that there should be a vacuum in the condo, because we wanted to clean the rooms by ourselves after coming home from the beach and maybe bringing some sand into the rooms - I guess if we would have asked Helen, she would have given to us too.
We had some issue about closing the window next to the bed, but that wasnt a big problem because it was hot all the time that we stayed in Sydney - but maybe should be fixed for the cooler days ;)
One thing my girlfriend would have also liked are curtains at the windows.
All in all we had a great time at Sams place and everything went fine from check-in until check-out.
