Joey was wonderful and the location was perfect for the purposes of our meeting, especially considering it was a last minute booking and time was so limited. She was really helpful during the whole process and would absolutely recommend. Thank you once again! Best wishes, Zara

Wonderful room and fantastic staff. Everyone was very happy.
The catering was a little disappointing. Everything was on time for our meeting and the coffee and tea options were great but the pastries were very small and not very appealing and did not feel like very good value for money.
