Despite having "Gold" Expedia status ("VIP Access"), I wasn't offered a room upgrade and didn't receive any other benefits. Also, the price was not as discounted as Expedia will have you believe.
The hotel itself was superb. Whilst the single room is small, it is well designed with a spacious, modern bathroom. All fixtures and fittings worked normally and were clean. Room servicing was thorough and all staff were polite, efficient and welcoming. The location is just a few minutes' walk from Earls Court tube and there are plentiful restaurants, shops, bars and fast food outlets nearby. The area felt safe and was quiet. The only significant noise came from the occupant in the room above me who appeared to be taking their pet elephant for a walk.
