I stayed there last October. It was going through some upgrade construction at the time. It had just become a Hilton. Was pretty nice. Not real near downtown. 5 minute walk from Paddington station in one direction and 2 minutes to a tube station in the other direction. Very convenient. About a 10 minute walk to the Marble Arch and Hyde Park where you can catch the double decker tour buses. Lots of shops nearby and little restaurants. Even McDonalds and Starbucks are a 5 minute walk if that is what you want for quick. I did not mind not being in the middle of downtown as it was very easy to get to.
