This flat is in a perfect location. Kings Cross puts you right at a crossroads for most of the rail systems. There are a few "left luggage" locations right near as well. The bed was very comfortable. My only struggle was the bathroom. It was very tight. I am 5'10 and 200 lbs and it was a squeeze to get into the shower.
That said, if the opportunity arises we will likely stay there again just because of the location.
