Simon's place is a perfect location for people visiting London. It is located in Zone 2 so travelling by bus/tube is very convenient. It about an 8-minute walk to the Westbourne Park tube station which makes it easy to get to the airport (via the Heathrow Express which can be accessed from Paddington Station).
Our room was clean, the bed comfortable and the bathroom and toilet w I ell-maintained. I would recommend this place the next time you are in London.
