We have a 24hr layover in London, while in route to Warsaw. Arrive Nov 25 8:30am and leave the following day at same time. From what I read the hotels by the airport are not that great overall, with long transit time to LHR. Last time in LHR we stayed by Victoria station and it was good, however the transit back to LHR was a bit time consuming. I prefer something with short transit to/from LHR, but with some local scenery, perhaps Paddington, or other suggestion. Thanks for your help.
