The location of Liz's flat is incredible! It was only a 12 minute walk from Paddington Station, where the Heathrow Express ends and a few minutes walk to the Marble Arch tube station. Also, it is across the street from the beautiful Hyde Park and just down the road from fantastic shopping.
Liz answered all my e-mails immediately, offered great restaurant suggestions, and was incredibly understanding when I was a bit late due to passport control at Heathrow.
The room is clean and comfortable. Would definitely recommend.
