As mentioned by other reviews. If you are looking for a clean/affordable place nearby Heathrow's airport, this is the place. Mandeep is a nice guy who helped right away (asked for extra towel and was there in a few minutes).
The only "negative" comments might be
a) bad WiFi signal: I couldn't connect at all, while my wife had a poor signal
b) there was no soap, but we really didn't ask Mandeep since we brought some with us from the nearby convenient store when we went out.
