Arrived at hotel. Concierge suggested park own car so what's the point of the valet? Told that there would be noise in ballroom until 11pm so requested room change to quiet room. Returned to room at midnight noisy function still on. Told mistake by banqeting. Staff promised quiet function still on at 1.15. Couldn't sleep so asked for car which... more

I have recently just returned from the Marriott Grosvenor Square Hotel staying there for a two nights to attend a conference and awards gala dinner with my husband. Check in was swift and the receptionist very friendly. Our room was lovely - nicely decorated, very clean with enough space. The bed was huge and the most comfortable bed I've slept... more

Stayed on business but accompanied by my wife partly as it was also our wedding anniversary. Ideal location just off Oxford street and Bond Street surrounded by restaurants with Gordon Ramsey's Maze within the building. We had a Club room that had its own patio garden within the hotel's central courtyard. Semi-private quiet outdoor space in Mayfair! (admittedley overlooked by... more

Even London's Pret-A-Manger outlets offer free WiFi/internet these days. Yet this Marriott wants $15 pounds day (say $26 USD a day!) for in-room internet connectivity. There is NO free internet access in the lobby. Forget their business center - that is just as expensive (and who knows what additoinal charges will accrue once you've wandered into their business center). This... more
