GooglePerfect, just turned up on spec, asked if there was a space I could rent. Everything was explained in clear terms. Was shown exactly the perfect space. Everything I needed from packing boxes to a padlock for unit were available on site. Signed up online process, simple and fast. Competitive pricing, half price for first 8 weeks rent. Spotless place. Friendly knowledgeable staff, big thanks to Neil who helped me set this up. Can’t fault all very safe and secure .

GoogleThese days we are so used to the meaningless platitudes of 'have a nice day', 'pleasure to be of service' etc that one almost doesn't hear them. The staff at Big Yellow in Cardiff were unscripted and sincere in their manner but more than that they actually were helpful when I needed them to be particularly near the end of their shift - no hint of impatience or 'dozy old codger' jus simple courtesy and excellent customer service. Neil in particular was of great help so my main praise is for him. the others were exemplary too. Highly recommended.

GoogleFirst of all, I must point out the fact that everyone working at this facility deserves a pay raise. There is no way BIG YELLOW is paying them what they deserve and are truly worth. The team in the Cardiff office doesn’t believe in or adhere to mediocrity. They believe in the “sky is the limit” philosophy. They far exceed the norm, and work tirelessly at an elite level. They are absolutely phenomenal. I’ve never seen a staff of people so capable and skilled in multitasking. They will do whatever it takes to assist patrons, and to ensure everyone experiences the supreme level of customer service synonymous with the BIG YELLOW brand. They are all very kind, personable, understanding, and highly professional. Sian and Denise are astoundingly astute, and sincerely work with every potential and current customer to help fulfill and maintain their optimal storage needs and expectations.
This storage space is impeccably maintained and much more clean and pristine than any we have ever visited. With climate control throughout, security alarms and private settings, safe reinforced contained areas, above adequate lighting, after-hours services, and much more - it stands as the preeminent choice for all business, office, and storage needs. Truly worth every penny spent.
Marcus is a most impressive manager and leader. Highly visible, available, and capable, he never stops working. He exudes invaluable insight, and is equally eager to assist, work with, and maintain all guest tenants. His managerial style has been carefully honed by necessity and perfected in brimstone and fire. On any given day, Marcus and his team face numerous challenges, chaos, and the unexpected. They work together to overcome each with a symbiotic style and inimitable sense of teamwork and confidence. Marcus leads the office by genuine example, personally tackling every and all issues which may arise. He is willing to step into any situation, and doesn’t shy away from difficult or complex problems. He exudes all the qualities and characteristics proven necessary to succeed. He is discernibly invested in Big Yellow’s future success, and stands as a living testament to their “next level” customer service philosophy and foundation.
I clearly recall obtaining the initial storage when Nathan worked at the helm in that office. That was over a decade ago, and yet somehow this location still magically maintains this same core group of remarkable people. Nathan proved to be an exceptional manager, who set a fine example for all of those to follow in his wake. All of the associates named above were there from my initial storage tenancy as well, which truly reflects on the ability of Big Yellow to retain stability and longevity within their ranks. Such loyalty and actions speak volumes, much more than mere words can convey. There is a shared and refreshingly profound sense of conviction among this team. If they are not viewed by corporate as the premiere top office, they most definitely should be.
The four people named above are much more than deserving of any rewards and recognition such a review warrants. I truly hope that each one receives their proper due, and that Big Yellow truly SEES and appreciates these superlative people working the trenches in the front lines of their business (day in - and day out!). There are many comparable storage competitors in this market from which to choose. Yet, by far, it is the PEOPLE working behind the desks and scenes which make any business entity special. This is one of those unique situations, and the company and patrons reap all of the benefits as a result. Thank you BIG YELLOW, for attracting such a memorable and capable longstanding team of individuals to operate together under the Cardiff Storage warehouse roof. Their collective proverbial “floor”, is all other storage facilities ceiling. They only see the possible, and that makes all the difference in the world.
