Time Out says
The cryptically named Time Resort entices passers-by with a gaudy neon sign and a mysterious ‘radon bath’ that appears wine-coloured thanks to its shimmering red tiles. After entering, close the door behind you and soak away – the sauna-like effect is supposed to be a potent cure for lingering tiredness.
