Thank you very much for all your help in planning last evening’s event. It ran very smoothly and was a huge success! Thank you AV Team as well!

Caitlin MacDonald, Progressive Media

Thanks to you and all the staff at RSM, in particular Karen, Dionne, JJ and reception team.  As always they are all so incredibly helpful which makes the event so much smoother.

Please pass on to all – and thanks again to you, for your patience with me as I make changes until the last minute!

Steph Maunders, Frogmore

I know when I came to do the site visit earlier this year I was impressed with the facilities and what you had to offer.  Now having held an event at the venue, I know that everything you promised was true. The service from the minute you walk in the door to the minute you leave, is excellent. I hope we can put other events to the venue.


From the whole Woolf family thank you all so much for facilitating such an excellent party for Dad. Your staff were all wonderful – the service was faultless, the food was very good and the venue was impeccable. We are all extremely grateful to everyone at 1 Wimpole Street for making our event such a success.

Serena Woolf, N/a Private Party

1 Wimpole Street is an excellent venue with great conference & AV facilities, good catering and above all exceptional staff.
