If you need a place for a night just around 4 km from the airport this is a great place where to stay, especially if it is a last minute arrangement: Sam will reply your enquiry straight away and help you if problems occur.
If you need to be at the airport early morning I suggest to use Uber (it will cost under $10); regular taxi drivers may not be so keen to help you and other drivers are not really around before 6am.
The room is like a motel room and the water pressure in the shower is great. I had some problems with cleanness of the bed- it seems that somebody, a little one- had used it to play- Sam promised not to charge the cleaning fee and I slept using my linen. Trusting that this does not happen normally I would go back to the same place in case of an early flight from Melbourne.
