Upon calling this company to clean for me, I have to admit, i was a bit skeptical. Nevertheless, upon arrival (in which they were 5 mins early i must add), they greeted me and asked if there might be anything specific that I would liked cleaned first. I've had cleaners come into my private office before to do work, no one has ever asked me that before. I found that to be quite flattering. The entire office is roughly 1500 sq ft with 3 work stations. I was impressed with the time in which they were able to complete the job. Upon offering them a tip, they denied and only asked that I refer them to friends and colleagues alike, as well as, provide their company with a review here on thumbtack. So, here I am! haha... Awesome job guys! I highly recommend!
