JW Marriott Grosvenor House London, Great Room

Wow, what an incredible stay we had at The Grovesner! From the moment we checked in, everything was amazing. Sofia and Hollie went above and beyond to make our visit truly special – thank you both for your outstanding service! The food was exceptional, and the live pianist added such a lovely touch to the atmosphere. Our room was stunning, especially with the complimentary upgrade – such a thoughtful gesture! To top it all off, having a bottle of champagne delivered to our room as we prepared for our awards ceremony was the perfect surprise. We are so grateful for the care and attention we received. Sofia and Hollie, you made our stay unforgettable. Thank you again for everything! Best wishes, Bessie & Paula

Organizing an event at the JW Marriott Grosvenor House London, was an amazing experience, and I would like to give a huge shoutout to the incredible staff. The location itself is stunning—right in the heart of London, with a gorgeous and classy vibe that made the event feel extra special. So many guests commented on how beautiful the venue was, and I couldn’t agree more. What really made the whole experience stand out, though, was the team. They were just fantastic—so quick to respond to any questions or requests, both before and after the event. On the day, they were everywhere, making sure everything was running smoothly and that everyone was happy. The JW Marriott Grosvenor House team was not only professional in executing the event, they were also very flexible to implement any last minute changes and gave recommendations on how we can streamline the processes and make the event even better for our guests. So many people told me how friendly and helpful they were, and it’s true: they really went above and beyond. The event itself was a big success. Everything was perfectly organized, from the setup to the food and even the little details. You could tell they’d thought of everything, and it all just felt effortless (even though I know a ton of work must have gone on behind the scenes!). All in all, I couldn’t be happier with how it turned out. If you’re thinking about hosting an event there, do it. You’ll be in amazing hands, and your event will be unforgettable.

Rooms are spacious. Location is superb. Service is slow The JW Marriott Grosvenor House London is a luxurious hotel located at 86-90 Park Lane, right in the heart of Mayfair. This prime location offers easy access to iconic attractions like Hyde Park and Buckingham Palace, making it a favorite among tourists. While the hotel exudes elegance with its stunning lobby and beautifully decorated rooms, it is often very crowded, especially during peak travel seasons. Unfortunately, this can lead to long wait times for check-in, which may be frustrating for guests eager to settle in. Despite the high-quality service from the staff, the sheer volume of visitors can make the check-in process feel like it takes forever. Once settled, guests can enjoy the spacious rooms equipped with modern amenities and plush bedding, ensuring a comfortable stay. Overall, while the JW Marriott Grosvenor House provides a luxurious experience in a fantastic location, be prepared for potential crowds and longer wait times during check-in.
