Old Street is a very good spa. It was built in the 1920’s and has impressive original Art Deco features(all marble and tiles.) But it was restored a few years ago and has clean, up-to-date facilities. There are extensive facilities including 2 saunas, 2 steam rooms, plunge pool and Roman style tepiderium, laconium and calderium. The salt scrub treatment I had was well done and my skin felt so soft after. The prices for entry and treatments were very reasonable too.
Nice place, chill room had no cups though and the reception staff could have been a bit more cheerful. Had a gorgeous facial though, really lovely lady.
