"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!"
