Great efficient hotel. All details correct, 2 upgrades for colleagues. Warned by reception that a party/disco still had an hour to go and was offered a higher floor room. Would suggest that a room NOT on the front is better - general noise all night and lorries/trucks from 0600 hrs. Will go back though - lounge for Gold Elite good... more

Just returned from a few days at the Grosvenor House Hotel in London. This has recently been taken over by J W Marriott hotel group. When we arrived our room wasn't ready (we were a little early) so we went straight to the executive lounge on the 7th floor where we had snacks and drinks until our room was ready.... more

I have stayed in Marriott Hotels all over the world and this one really does not live up to expectations. The good news is that if you want a location that is in the Mayfair area then this fits the bill. The bad news is that there are a lot of other hotels from which to choose and you just... more

We were booked into a Club level room, and were pleasantly surprised by the size and decor (we had one of the newly-decorated Club rooms, with a small patio). Our parents (in their late 50s) were previous fans of this hotel, but were rather disappointed that the Club rooms were now very modern, rather than their previous "Chintzy" style. I... more

Our recent stay at the Marriott at Grosvenor Square was to be expected for a large Marriott. The location in the Mayfair neighborhood is perfect, providing walking access to thoroughfares like Oxford and New Bond Streets, and neighborhoods like Marylebone, Soho, Knightsbridge, Westminster, etc. Marriott Grosvenor Square is also home to a Gordon Ramsey restaurant, Maze. The rooms are extremely... more

Stayed in this hotel for only a couple of days but wish it had been much more. We used our Marriott points to book a room and were upgraded to a suite on check in. The suite was fantastic- huge living room and lovely large bedroom and bathroom, lovely molton brown toiletries finished off my excitement with the room. The... more

Stayed here on Marriott points, arrived in the morning, and were not impressed at reception being told we could come back later to stay in an inferior room. However, the supervisor sorted it out - and found an already free room for us, which was great. Our room was fairly small and had thin walls, but was very nicely furnished,... more

We were very disappointed in the Marriott Grosvenor Square Being platinum members you get used to upgrades, we were not upgraded. They said the hotel was booked. The safe did not work, the shower head leaked all over the floor and there was a huge wet brown spot on the carpet. We asked for a different room and was told... more

I paid $ 575 for one night in a " DE LUXE SINGLE ROOM " and they placed me on the first floor upon the rubbish dump of the hotel and stuck to the scaffold with the rubbish slope. Realized all this when at 7,30 a.m. the suppliers truck started parking under my window. I complained about it and the... more
