Marriott Hotel Grosvenor Square, Westminster Ballroom

I absolutely love this hotel. I frequently travel for work, and the last time I was in London I stayed at Grosvenor House and had a great experience. I loved it so much I decided to come back with my family for spring break. The hotel is beautifully designed -- charming and elegant. I have Platinum Marriott status and thus had access to a lounge that had a breakfast, snack and cocktail/light dinner service that exceeded all expectations. The food and drinks were delicious. The champagne choices during cocktail hour were particularly exceptional! The staff at every step was flawless. From check in to the cleaning service to the people in the lounge, people went above and beyond to make sure our whole family was taken care of. I was amazed at how attentive everyone was to my kids, too. The kids (aged 5 and 7) got coloring books and a stuffie when we checked in, and in the lounge the staff frequently checked on us to make sure the kids had the right foods to eat. Everyone went above and beyond to help us and it made our stay extra magical. Finally, the location of this hotel is ideal. You're right across the street from Hyde Park and have access to all the shopping and restaurants of Mayfair and every transportation option you could need. Yet you also are in a quiet neighborhood somehow. My daughter and I went on morning walks and enjoyed the quaint streets immensely. I highly recommend this hotel!!

I was invited to a wedding there. When just the orange juice at the foyer tasted like something I have never tasted before I just knew everything else was going to be on par and I wasn't wrong. The champagne was next....😏. I didn't stay there so I can't comment about the room but I have no doubt that they must have been exceptional.

Stayed for 4 days while visiting London. Stayed on one of the Balcony Suites with an outdoor courtyard and it was wonderful! The hotel is close to what we wanted in Mayfair. The staff was wonderful and the M Club lounge was a very good place to start our day with full breakfast (albeit in a lower level). No lobby to speak of but a nice bar and Gordon Ramsay restaurant are on site. I highly recommend the Balcony Junior Suite as it provided a nice place to escape that was semi-private, with (fake) fireplace, umbrella table, and chairs. Room has the king bed, a sofa/sitting area and large windows.
