My father used them for over a year to keep his business looking nice everyday. The cleaners did a good job leaving the place sparkly clean everynight.
When we arrived in the morning it smelled fresh and was VERY VERY clean. In a scale of 1/10, 10 being the best I give them a 11.
Richard was the person we spoke to, and he seems like a really cool, nice guy. Richard is the owner of the company by the way.
