The Lanesborough Spa is now open, so I was going to go along this week for a stay and check it out. Alas, Four Seasons Prague has taught me to ask in advance of exactly what they define to be a "hydrotherapy pool" and once again, in tradition of the great heat famine of 2017, it is a mere 28C. I can only assume all the water pumps have some rare material in them which meant they were confiscated and turned into the new iPhone 8. Maybe the hotels assume that with global warming there's no need to bother and soon rooms without central heating will be the next thing.
