We hired What Cleaning to manage our end-of-tenancy clean. They were prompt, professional and did an absolutely incredible job! During our check-out appointment, the inspector gave them full marks (and we’ll get our full deposit back!). Really top notch job for a very affordable price – couldn’t be more pleased!
