I'm arriving at Heathrow on a sunday night at 6:30pm and my connecting flight leaves at 9 am on Monday morning. I plan to stay as close to the airport as possible but would like to be able to walk to a subway station for a quick trip into London Sunday night. Can anyone recommend a hotel? Thanks.
There is a Yotel IN Heathrow. Google it for details...but I'll tell you up front, it is clean and with everything you need, but Tiny. You can board the subway in Heathrow as well, although if time is precious for you (as it appears to be from your post), you might be better off taking the Heathrow Express to Paddington Station. It costs about 7 times the tube and takes 1/4 as long. You might want to delete the duplicate post so other posters can reply to this one.
The Jurys Inn would fit your needs. It's close by the Hatton Cross Underground station and riding city buses between Heathrow and Hatton Cross is free. See here: http://tinyurl.com/299qnu5.
