We have booked rooms at Parkwood Hotel (4 Stanhope Place, Marble Arch, Westminster Borough). I've read reviews and they are good. I understand there is no elevator. We're only there for 2 days prior to our cruise. We are an active group and plan to walk to most attractions (Buckingham Palace, Westminster Abby, Big Ben, St Paul's Cathedral and Tower of London). Can anyone familiar with this area advise if this can be done in 1.5 days?
