Room for solo travellers in Euston

Mixed experience. The room was perfectly fine and the location near Euston station is hard to beat, which is why I am giving credit where it is due. However, the front desk let the stay down. I arrived at 2:45pm and was asked to wait until 3pm, which I accepted, but I then watched another guest who arrived after me, also without early check-in, get checked in straight away. Despite arriving with luggage and a visible mobility issue, I was allocated a top floor room at the far end of the corridor, a long walk each way. My key card also deactivated,, and each trip back to reception to fix it was met with a curt, unfriendly manner. With a bit of staff training on consistency and courtesy, this would be a solid place to stay.
