The prompt and courteous service was most satisfactory. I found my residence sparkling like the day it was built. I never normally pull myself together to write a review for a company, but this one, Harrow Cleaners, was really a total and utter exception to the rule. I will be informing my friends duly about the marvellous work they did in the bathroom. The glass on my shower door is forever covered in water marks, but the cleaners made it so clear I didn’t even know it was there! Absolutely transparent. No marks at all. I simply don’t know how they did it. I’m incredulous. Highly recommended.
