Meeting · 28 guests · September 2025 · Hardy Room

A bright, airy, spacious room in a wonderful central London location, with ample room for everyone. Tea & coffee was served on time and with the dietary requirements I'd specified. Tech all worked brilliantly, with a little bit of guidance from our host, Meg. We really appreciated the venue accommodating an external company coming in and running a corporate art class with us – not all venues I spoke to were open to this! We'd hire this space again :)
