I recently reserved the Marble Arch Marriott in London for 4 nights for an upcoming trip to London in late May. The more reviews I'm reading it sounds like the hotel is not in a desirable area of the city and the hotel itself is a bit dated. I'm debating changing my reservation to a different Marriott property in London that is closer/walking distance to the major sites. Can someone please recommend a Marriott in central London. Looking to pay less than $300 / night. Or use points + cash option. Thanks!
