Always use this service to get to and from Sydney Airport especially early flights when I can't ask a friend. Cars immaculate, they take time to ensure your child is restrained properly.
Expensive yes but how much is your child's life worth?

On checking trip advisor for transfers to the city from the airport I was somewhat deterred by the posts for some of the companies operating taxis etc .
On reading a review on this company I contacted Bubs Taxi to see if they only transported families.
It turned out that they also have a taxi company which we eventually used.
My query by email was returned promptly with all the details I needed .
I subsequently did all the arrangements over the phone and confirmation was sent back via email.
All very quick and efficient, as we were travelling the next day.
On arrival at the airport we were greeted by the driver who was in the exact place they said he would be.
He handled all our luggage to and from the car and gave us some information about Sydney, the special lights festival being one of them.
We were grateful for this as we would have had no idea this was on otherwise.
He provided excellent service.

I would thoroughly recommend this company if you are prepared to pay for the service, we just wanted to travel with a reliable service provider.

We booked a return transfer from airport to hotel. We were met by Brendan at the airport then Ray for the return trip. Both trips were taken in a very comfortable maxi van. Both drivers were friendly and knew the city well. They both helped with luggage and also with opening doors. They both checked the car once all passengers were out for any leftover belongings, this was a nice touch because it's very easy to misplace things with children around. The car seats were in excellent condition and I felt my 1.5yo and 6yo were very safe and secure. We took up the special Facebook offer of a free pram hire (when booking a return transfer). The pram was a nice model, very light and easy to fold and to get around the city with. It was great not having to drag our pram around the airport and check it in.
During our stay in Sydney we had to call a normal cab due to rain and we didn't feel like our children were as safe in that as we did with Bubs Taxi. Would definitely use Bubs Taxi again and would highly recommend.
