Beautiful hotel, right beside the Marble Arch underground station. Excellent staff. Great lounge if you have access. Used my suite upgrades for three nights in 254 - a spectacular suite. Good gym and pool as well.

We went for afternoon tea which was nice and the reason for 2 stars rather than 1. We were offered an upgrade of a birthday package. This was an absolute disappointment and waste of money. It was sold as a private room with views looking over marble arch, birthday decorations, balloons, extra time and a birthday cake. The birthday cake i was charged extra for even though it was meant to be part of the deal. Close to the date i was called and asked if i would mind having a different room as they were going to be doing some filming which i agreed to assuming that the other room would be equal to the room outlined before. This was not the case i was given a room that was downstairs and had a view of a concrete wall a foot in front of the window, My decorations were a little bit of paper confetti sprinkled on the table with a few sweets some of which were just wrappers as the sweets had already been eaten. the balloons were 3 balloons that were very small just sat on the table one of which was half inflated. Its definitely not an experience i would do again and but a large dampener on my birthday celebrations as this is not a standard i would expect from the Marriott.

Was reticent about a Marriott but my stay was superb - old world charm, impeccable attention to room detail/amenities, fantastic executive lounge & restaurant, spotless marble bath/showers & toto toilet. Within walking distance to Mayfair (shopping district). Highly recommended.

The hotel is great and really nice room, but I think they have a problem with the house keeping stuff. They kept the tea cups unclean for days, and if they clean it and then we reuse they also stays unclean for another few days until we ask again from them to clean it. But despite this issue, we enjoyed our stay there.

Exceptional Service! The staff was highly professional. Interior was so beautiful. Overall my experience with this hotel was positive. Highly recommend.
