We loved our 2 night stay at 45 Park Lane. Everything from the door man to checking in, to our room upgrade, to the knowledgeable bartender in the evenings, everyone went out of their way to make our stay so special. We accidentally left our 'do not disturb' on when we went out for the day, and they did not hesitate to clean our room late in the evening after we had returned. Amazing service, prime London location and beautiful boutique hotel!
