Chris helped me set up my space. The premises were amazing and so clean, the app was comprehensive and easy to use and I didn’t even need a padlock. They even offered desk / office space as part of the package. Wow. So impressed with the service.

Tayo is the hero of the day, he stayed late after closing just to give myself and my girlfriend a top class experience that I do not think you could get anywhere else. Despite only being there a few months, he truly went above and beyond to represent the company in a more than perfect way. I can only thank Tayo for his great duty and bless him. The company is lucky to have such an employee. I hope to see him run the place one day.
