I can recommend Clive's room. It was clean and near to the station. You can be in the city centre in 20 minutes. Clive will help you get to the flat from the airport and will meet u on the station what's really helpful. In the room you can find some London maps and information about the trains, alarm numbers and places to go. You can also count on Clive when you won't know sth like where to print sth or how to get to some places. Clive is a very very nice person and I'm really grateful for his help, everything was fine so if your'e looking for some room to rent you don't need to hesitate ;)
