A great location - less than 5 minute walk from both Charing Cross Station and Embankment Station. Right next to Trafalgar Square. So convenient to everything in Central London. No key lock box - you need to meet a person to let you in. We were early and needed to wait 40 minutes for her to arrive. The flat is clean, but not in perfect condition. Door to one bathroom does not close all the way. Has a washer and dryer (small combo machine) but the dryer does not work very well (like many dryers in the UK). I would recommend based on the great location.
