We arrived at Sullivans by Taxi from the airport charge $40 AUD. Taxi driver was very informative. We had arrived short of a suit case and a stolen cam corder but were determined not to let this deter from our holiday. The hotel staff were very helpful, allowing us into our room early. The room was not too large but we were only stopping a couple of nights. The reception staff were very helpful regarding our luggage and guided us to how to get the best of the short time we were in Sydney.

I would definitely recommend position, quite a busy nightlife and plenty of boutique shops nearby. Just a short bus trip into the city and we had a couple of early morning strolls into centennial park.

Very centralized. Easy access to public transportation because the buses stop only a few step from the hotel.

Pros: Good location, free parking, very friendly reception staff who gave us lots of tips and advice on public transport and was very helpful with all questions we had.
Cons: Our room (it was room 113, so you can avoid it) stank of urine; it got a little better once we activated ventilation and the air conditioner, but a/c is automatically switched off once you leave the room so it does not help much. The room was very small as well and it was not perfectly clean. There was rubbish left from a previous guest in the trash bin.
There is free internet access from a computer in the lobby, but it was almost always occupied since there is only one for such a big hotel.
For Sydney, it is however probably one of the hotels with reasonable prices.
One last advice would be to avoid the airport shuttle which the hotel can book for you. When we were picked up, we were driven to another hotel and had to wait there for another vehicle for quite a time. It took much longer than we were told.

Pro's:
Quite good value for Sidney
Good public transportation just outside the door
Clean, basic room
Friendly staff
Free internet in the lobby
Allowed us very early checkin
Free movies
