Overall the place is good if you want to stay near Heathrow airport.
In regard of cleanliness and privacy, the place is perfect.
The down side is the heating system, I would request the host to upgrade it or something, the room was very cold, the heating worked for a short period of time during night time only (4hrs) except that it was not working.
You can find pretty much all basic cutlery which is a plus point.
There were two showers, one of them is tub which is cool but the other one (standing) is faulty, the mixer (hot&cold) doesn't work.
