The Team were fantastic to deal with throughout the planning process and even more welcoming and amazing to deal with on the day. They went above and beyond to adapt to our changing plans and the AV tech Thomas was fantastic.

I think if we hit our capacity (180) it would have felt too tight. Everything else was superb.

Conference · 60 guests · November 2024

I held a student conference at 20 Cavendish Square and the entire team were extremely welcoming and helpful through all of the steps, from first contact, to booking the venue, to helping us out on the day. Joey was an exceptional administrator and ensured the conference went smoothly for everyone. She was very approachable, friendly and efficient sith any requests that came up during the day. Will ran all of the AV facilities and made sure all of the requests were met. Perry, who was my initial contact on TagVenue also helped us throughout the day and was very friendly and helpful. The venue itself is beautiful and is in a great location. It is also fully accessible.
