Angela is a very nice and helpful girl, the apartment is very close to the Colindale metro station, it is very clean with access to the kitchen and fridge. A subway ticket from Heatrow to Colindale (Piccadilly and Northern line) costs only 3.10 Pfund on Saturday. I recommend it to anyone in this area, next time I am in London I will definitely come back here when it is free. Thank you very much Angela :-)
