All you have to do is to call them and make appointment with someone of the crew. They will come to explain you the whole process and give you quote. On very next day they arrived and started to clean almost immediately. The appliances and tiles really needed scrubbing, and they managed to get rid of all dirt that was build up there. They said that they will need between 4-7 hours, but they cleaned the whole place only for 3.5 hours, which was very amazing. When our landlord came to see our house, he was amazed and gave us our deposit back (the whole deposit!!).
