Don't do it. Worthless experience, horrible book-keeping.
Very quick in booking an appointment, asked very detailed about my ventilation, but then only spent 30 minutes actually cleaning 3 out of 6 outlets and charging full price.
After paying the full invoice, they continue sending me payment reminders. They do not reply via email (where I shared the payment confirmation) as well as a reminder that it was paid. and they do not pick up the phone.
