They might clean well... I wouldn't know. We scheduled two cleaning services for two separate houses on the same street almost a week in advance, they verified the service the previous Friday, and they cancelled on Monday, the day OF service.
They'd have penalized me for breaking an appointment day of service. Wish there was a penalty for them.
Very disappointed, as they were the most expensive quote I received, and let me down like I would have expected from the lowest bidder.
