Michael Diamond , a.k.a. Mike D of the Beastie Boys , made headlines in 2013 with his impeccably renovated Cobble Hill townhouse , which got a glowing writeup in the Times , and somewhat smaller headlines last week when it was discovered that a couple had, for still unknown reasons, used that house as a set for one of their amateur porn shoots . Now the house is on the market for $5.65 million , and would surely be an attractive offering even without the celebrity factor.
