Absolutely gorgeous little gem in the middle of the Sydney. I chose Bettina's place mainly for its proximity to the ICC. There is an overhead bridge leading from the second floor of the apartments into a parking block. Then take the elevator to Level 1, cross the road and you are at the doors of ICC. This all took less than 5 minutes. (You can ask the hotel staff the directions). It is also located very near a Light Train which can bring you into the City/Chinatown/Central Station. You can purchase an Opal transport card in Harbourside Shopping Mall which is opposite the ICC.
Apart from the location, the apartment is stylish and modern but also really clean. I personally love the little touches like coffee machines (with pods provided), selection of teas, biscuits, washing machine and dryer.
All in all, highly recommended to fellow travellers and would return to stay.
