I would strongly advise anyone not to use this cleaning company!
Optima Cleaners has provided one of the worst services I have ever encountered. They quote one price and then renegotiate the service price on the day of the bond clean. They misrepresent themselves as a professional cleaning company on their website but on cleaning day you will realise that they use unprofessional subcontractors. They promise to respond to issues within 48 hours but does not respond to ANY phone calls or emails. They did not clean the garage or the veranda as agreed, which I had to do myself afterwards. They did not dust nor clean the vertical blinds but merely folded them all up to hide the fact that they were not attended to. They do not honour their "Bond Guarantee" and wanted to charge me additionally for returning to clean the blinds! I had to organise a new cleaner to clean the blinds. And the list goes on ...
You will be out of pocket and left frustrated if you use them.

Approximate cost: $1100
