No refrigerator, elevators barely work, no real air conditioning (no thermostat, just a set of knobs for a room fan).
For a hotel this expensive, a mini-fridge is a no-brainer. If you stay for more than a couple days, you can't bring snacks or drinks back to the room - it will rot or get hot.
One elevator was out of order the entire time we stayed, for over a week. I don't think they had any plans to fix it. During my stay, I kept encountering people with suitcases waiting for an elevator, heading to their plane or train. Once an elevator arrived, it was packed with people with suitcases. We started just hitting the Up button so we'd get on -an- elevator and have a chance of going out. We adjusted by leaving 20 minutes early for our flight.
The beds only had thick blankets on them, not normal sheets. It was the summer, so you either had no covers or you'd sweat. The lack of the thermostat was an issue as just leaving the room fan on would make it frigid in the middle of the night.
The location was great. We were steps from the London Underground Piccadilly station, and you could literally see the hotel marquee once you stepped up to the street. We were walking distance from a great many landmarks - Leicester Square, Trafalgar Square, St. James Park, Buckingham Palace, etc. This had its downsides - the street was a mob after 10am and restaurants were super busy.
There was a massive gym and pool, staff was great, housekeeping every day, but I'd rather have a fridge.
