JW Marriott Grosvenor House London, Great Room

Recently stayed 6 nights at the Marriott Grosvenor House. My wife and I really enjoyed the stay. It's in a great location across from a park, and close to shopping and public transportation. The staff were friendly and helpful. The hotel is clean and well maintained. We were upgraded to a suite. Tons of space and a large bathroom. We enjoyed eating at the on-site Steakhouse. They did a great job of accommodating my food allergies. We really enjoyed the club lounge. The staff there were very helpful and friendly. Shoutout to Abdul and the rest of the breakfast staff! They even had Vegan yogurt as part of the breakfast! My wife thoroughly enjoyed the scones during the afternoon tea! And of course, the evening wine was very much appreciated!

The JW Marriott is one of the best "old school luxury" hotels is London. The location is perfect for both business travelers as well as tourists. You can always find some super expensive Rolls or Lambos parked in the courtyard. The rooms are nice, especially the ones with the Hyde Park facing windows. Service is done with typical British efficiency and courtesy. There are many decent dining option on-site, including the high-tea room.

Great hotel. We enjoyed staying there. We had Executive Lounge access but did not use it much. I had breakfast and dinner once, and it was ok. It cannot be compared with lounge @ Ritz Carlton for example. There is a cafe in the hotel, which is good. The coffee is great, and they had salad, sandwich, chocolate etc. The hotel is in Mayfair and in waking distance to most parts of London if you like to walk. Tubes are within 5 minutes ish. The gym is better than average.
