Did you mean?
Sg is small so it does not really matters if u are far from airport. Sightseeing is not near the airport. Taxi in Sg are all metered so there is no extra charge for journey starting from a hotel. Most hotel around the Raffles Hotel area are 5*.
Hotel is okay. Not near airport; I thought it would be. BEWARE taxis at hotel; probably rip offs. Stay at hotels in area around Raffles Hotel.
It is my pleasure. I hope it all works out for you. Hope Sydney (and the Metro) don't disappoint.
