As Miss Cyril "Cilla" Black might put it, there's been a lorra lorra history in these rooms. Plus a lorra lorra skag.
For this was once the second floor flat cum "salon" of art dealer to the stars Robert Fraser, much frequented by Paul and JohnandYoko. Here they would come to hang out with passing Pop artists, indulge in whatever might be indulgeable (pretty sure that's not a word), and lend unrecoverable sums of money to the titular Bob.
Fraser, o' course, was also well in with the Stones, and it was whilst looking out of these very windows upon a storm-lashed Mayfair that Keef wrote "Gimme Shelter":
Mr Richards also recalls, in his highly entertaining memoir, how Fraser would often disappear off to riffle through the pockets of the finely cut suits hanging in these very "cupboards", seeking stray heroin "jacks":
Pharmaceutical heroin was available on the NHS back then, provided one was a registered junkie. The musicians' chemist of choice for this purpose was, apparently, John Bell & Croyden of Wigmore Street; still there, though no longer a dispenser of "doojee".
