Did Sussex this past weekend for a night. Booked a single room, upgraded to a King Deluxe. Room was nice, staff was pretty good. A bit of noise from the street (entrance side). Trucks making noise until about 1am. Only complaint was I got paint on my jacket and backpack as they were doing some painting w/o signage (later posted signs). I didn't do breakfast. Very close to Hyde Park, shops on Oxford street and about half way from either Bond St or Marble Arch tube stops. Central line was closed on sat/sun, so made it a bit difficult. I may try the Mayfair out in about a month.
