Testimonials

"We held a fantastic corporate event at St Marys Marylebone in Nov 2023. The venue were very professional to work with in advance and onsite. It's cost effective, supportive staff and their recommendations of caterers worked well too (we used Little Piggy and would 100% recommend!). We will definitely be back for another event. Cracking venue!"

GCVA

"My husband and I hosted our wedding reception at St Mary's on the 20th May 2023 and honestly could not have been more thrilled to have found this gem of a venue in such a prime location in London! Megan, Charlotte and their team were such a joy to work with. They were professional, courteous and went above and beyond to make sure we were prepared for our big day! We cannot recommend St Mary's enough, book your venue visit asap!"

Lemaat and Marcos

"We had a great time hosting our charities first ever National Conference at St Mary's. The venue was beautiful and the staff team could not have been more helpful from the initial enquiry right through to the running of the day. They made it all so easy for us. We used one of the venues recommended caterers, Gurkin, who made us beautifully presented and really tasty food to treat our guests with. We will definitely be returning for our next conference ."

Baby Basics

"Lucy and I could not be more grateful to St Mary’s for making our wedding day so incredibly special and stress free. Charlotte and Megan were fantastic throughout the planning process and ensure everything ran smoothly. Their attention to detail was exceptional and they went out of their way to make sure the day ran exactly as we planned. St Mary’s is a stunning venue, beautiful on the inside and out, and was the perfect place to host all our loved ones. We will cherish our memories created there forever."

Lucy and Joe

"Fantastic venue, with exceptional service and responsivity in the lead up to our event. The onsite team are so helpful and friendly, and I can't wait to hold our event here again next year. Highly recommended"

Glendower Prep

"The staff and venue was absolutely amazing. We hired the venue for our charity walk start and finish location and it was perfect. We had around 900 people in total walking for us that day and it was a real success. Pre event the staff were super helpful and knowledgeable and made us feel really confident about the event as did the on the day team. Thank you so much for helping us deliver a fabulous and memorable day for our community."

The Brain Tumour Charity

"We organised a two day event at St Mary's London for 300 healthcare professionals. The hall certainly had the WOW factor and the staff were all extremely helpful in the lead up to the event and on both days. It's a long time since I've used a dry space but they made sure nothing was forgotten or left to chance. It was such a success that we hope to repeat the event at St Mary's next March."

Neil Stewart Associates

"We recently hired this venue for a wine tasting event and it was a big success. The venue team were a delight to work with and made the organising and running of the event really easy. There is a lot furniture on site which you can use and the built in AV is also a great bonus. We will definitely be using this venue again."

Agile Media

"As an event organiser I have worked all over the world and this is now one of my favourite venues. I think it is perfect for all kinds of events and the acoustics for live music are amazing. The team are a dream to work with and very helpful and accommodating. I would highly recommend St Mary's as one of the best hidden gems in London."
