Fab service and delicious food! I had my wedding at the Marriott in Grosvenor Square in July 2023 in the ballroom. Was so pleased with the service and delicious food. So many of our guests said they've never tasted food like that at a wedding before. Castro head of food and beverage was fab and chef Graham did a fantastic job. Of course we couldn't have done this without our wedding coordinators, Marilyns. Thank you to everyone :)

Our wedding was truly an unforgettable experience. The staff, Castro and Chef Graeme went above and beyond for us, and we appreciate everything they did for us on the day. Everyone was accommodating and met every need we had to make our day as special as it was. A huge thank you to Costa and Christina at Marylins Weddings. Their fantastic relationship with London Marriott Grosvenor Square helped to pull off the wedding of our dreams. We truly cannot thank you all enough. Elaina and Chris, the happy newlyweds xx

My wife and I shared our big day at the Marriott Grosvenor Square and it was the best decision we made! Staff were very friendly and welcoming to all of our guests; leading up to our big day the events coordinator, Joanna, provided us with all the support we needed to ensure the running of a smooth day and so it was. Would highly recommend this hotel to host all the private and corporate events. Thank you Marriott, Joanna & Team!
