I had a massage with Than and was underwhelmed, sadly. He's a sweet guy, and has a beautiful spa-like set-up in his studio apartment, but he is untrained and his massage is unfocused and boring and not sensual. I did leave happy, which was nice.
You could get the same experience from an inexperienced/beginner masseur in any of the men's spas around the city, although Than's set-up is infinitely nicer.
Be warned: he has a very well-behaved cat, in case you're allergic.
