“We held our first event at this venue yesterday and what a great event it was. The Cowdray Hall and Council room worked beautifully for our event, with high ceilings and windows the room felt very airy. Very helpful staff and event management by Rasa Turner. The catering was excellent and we had great feedback from our clients on the new venue. We look forward to our next event in September.”

"I booked Cowdry Hall and the Council Room at 20 Cavendish Sq for a student conference. I was thrilled with how the event turned out. Joey, Will and Perry were all extremely friendly and helpful throughout the day, as was Jack and the rest of the catering team. The venue is gorgeous, fully accessible and everything went smoothly. The space can accommodate for a range of different events and worked perfectly for our conference."
"We hosted two days of meetings at 20CS and had a great experience. They catered to all our needs and ensured the event ran smoothly. Special thanks to Joey who looked after us. The food was great, we would definitely use the venue again."
"As the Mindful Business Charter we ran our first all day conference for members at 20 Cavendish Square. As our first such event we were inevitably learning as we went and a little nervous. We felt so well cared for and safe with the wonderful team from 20 Cavendish Square. The facilities are magnificent but what made the day was the support we had throughout from every member of the team. We will definitely be back."
