"By the far the worse serviced office provider I have every come across and it's not even close. Suggest anyone looking at this to check other properties instead: 1) Lift availability: One lift has been out of service for most of the past two years and has never been fixed. The other lift works most of the time but is occasionally out of service, meaning anyone working there must walk up to the max 5th floor. I would not recommend renting above the 2nd floor. Communication regarding the permanently out-of-service lift could also be improved as it's basically non existent (re: point 8). 2) Toilet cleanliness: Toilets have consistently lacked proper cleaning and hygiene. See for yourself when you check it out. 3) Room cleanliness: Our rooms have gone uncleaned for extended periods, likely due to disputes with the cleaning contractor. 4) Kitchen cleanliness: The kitchen area is not maintained to an acceptable standard. See for yourself when you check it out. 5) Door maintenance: Our door has been slamming since day one and remains unfixed despite multiple reminders. 6) Post handling and notifications: Charging £14 + VAT for delivering uncollected post to employees was unexpected and is not mentioned in the T&Cs. This creates additional cost and inconvenience for the employer and seems inconsistent with the current work-from-home environment. 7) General building maintenance: Overall maintenance has been subpar. See for yourself when you check it out. 8) The property manager actually doesn't care since it's well above his pay grade. He's just a paper pusher. That's life with Regus, you pay peanuts, you get monkeys. Avoid at all cost."

"We’ve been renting our office space with Regus for several years now and have no plans to move. The team led by Davide is always accommodating, helpful, and professional. They made our recent move to a larger office seamless and continue to provide excellent support whenever we need it. Highly recommended!"

"I had an appointment with one of the offices here and the buzzer didn't work either even after a several attempts. I was out waiting in the heavy rain for 10 minutes with no one answering the intercom. Finally managed to get in when someone politely opened the door for me as they were exiting. I went upstairs and receptionist was just browsing on her phone. Seemed annoyed I was disturbing her. Very bad service and please sort out your intercom!!"
