I was recently asked if I have a favorite hotel in London. I’ve stayed at a number of luxury hotels in London over the years, but, on my recent visits, I have stayed with friends. My assessment of the best hotels in London may not be too accurate.However, I do know that one of the most expensive and luxurious hotels in London is the Lanesborough. I recently found out the Lanesborough was originally St. George’s Hospital, opened in 1733. In 1991, it opened as a Rosewood Hotel & Resort and then, in 1993, it became a St. Regis.This knowledge reminded me of an Istanbul property. The Four Seasons Istanbul was originally the first jail house, built in 1918 during the Ottoman Empire. It was abandoned in 1969, later used by the military and then finally transformed into a world-class luxury hotel in 1996.While both of these properties were gutted and completely renovated, I can’t help but think about what happened in those halls when they were a hospital and prison, respectively. If I’m asking if you believe in ghosts, I also have to ask if you believe in mind over matter. While I have not stayed in either hotel, I do know both properties are known for superior service and luxury amenities. However, if I were to stay in either property now, knowing the history, I dare say I would be a little on edge, wondering if ghosts are really wandering the corridors!– Alex Young, vice president and associate publisher
