Blow Up Hall 50/50 is a complex that includes a restaurant, art gallery, and hotel. It commissioned its hallmark installation to be designed by crucial artist Rafael Lozano-Hemmer, one of the world's top digital artists.
He is a BAFTA prize winner, and his work has appeared in New York and the Tate Modern London.
There is no reception or door numbers. Here, guests book, locate, and open their rooms with iPhones that use digital recognition technology to unlock doors.
Luckily the massages on offer are still done by trained humans in an old-fashioned way. Robot design hasn’t gone to the stage where they can give a good massage, as their hands are too cold.
You can also relax in the large steam room. The complex also includes boutique shopping in a nearby converted brewery. The restaurant is top-class, and the bar is resplendent in purple and geometric finery.
