"I have hosted 2 events at this space - the first one on the amazing rooftop! The second in the cafe area inside (due to wet weather). Both times my friends and I had an amazing time! Special shoutout to Karolina who took so much of the stress out of the evenings (hosting parties is not my usual thing). Would definitely recommend if you're looking for a great rooftop space with an equally excellent wet-weather back up plan."

"If you need a co working space, this would be your first choice! They have cupcakes every Tuesday at 3pm, breakfast once a month on Friday at 10am, drinks once a month late afternoon on Thursdays, free yoga and HITT classes twice a week and so many other things to provide a community feel among the people renting space in the many levels. There's showers, hair dryers and straighteners and also a roof top where you can chill for lunch or a few cheeky alcoholic beverages. There is also a cafe/bar on the ground floor and lifts if you don't want to use the stairs. Everyone I have spoken to, including staff and other renter are super friendly and genuine. They have lots of vegan snacks and options which is amazing!"

"I've been coming to Uncommon Borough for a few years now, using day/flex passes - such a great flexible office space to work! The whole team (Ren, Hats, Georgia and Karolina) are very friendly and always more than happy to help. The flex/co-working space upstairs is a bright space (with plants) to work, but also if needed, there are also places to take calls etc downstairs. Would highly recommend!"

"The best co-working space I've been to in a while - a perfect combination of an upbeat atmosphere whilst also being clam enough to work. The staff are super friendly and helpful, I split my water everywhere and they were up immediately helping me clean it all up. Would highly recommend! The coffee also keeps me coming back, especially when there are reward points!!"
