Wave is great! I have been using them for months and they always send very nice cleaners who are easy to talk to! They will usually perform special requests at no extra charge too!
They always go above and beyond what I expect even going as far to clean the dishes is my sink and put them in the dishwasher (did not ask, nor expect this). They have even vacuumed my furniture. They actually like cleaning and have pride in their work. They won't leave until they are happy with the job they have done, even if they have to stay a little extra time. They also do this for a fraction of the cost of some of their competitors.
Another big plus is they allow me to pay them using PayPal!
I highly recommend them, and will be using them as my go to maid/cleaning service for years to come!
