Not this trip, but I have stayed there many years ago. This time I stayed near the Burough Market for a few days, then a quick trip to Edinburgh, then a few days on the Strand and back home. I was visiting my daughter, who was living there at the time. She showed me all around.
I mention Mayfair because daughter and I stayed there during our visit in ´94, but it seemed more like visiting Saudi Arabia with all the burqas and loud Arabic parties every night. Maybe Kensington would have been better. But now having seen it, I don´t need to go back.
Best to You and Yours....
