Tania's place is very handy to catch buses and trains although it will take about 50 minutes to get anywhere. I feel that Tania's place is best suited for younger people as you have to go upstairs to the bedroom. I found this difficult particularly when using the bathroom and kitchen as I often forgot to take things with me meaning another climb upstairs.
Tania is extremely helpful however sometimes her advice about public transport is inaccurate. When catching the 105 bus from Heathrow you will need to purchase a card (Opal I think it is called) from the National Express Coach ticket office (£18 with £15 credit on it) or get it from the train ticket office/machine it will cost £5 then you will need to add credit to it. When getting off the bus get off at Greenford station - the bus will stop just short of the station and will sit there for a break. When getting off walk towards the T intersection (just metres away) turn left and go under the bridge. Cross the road at the pedestrian lights and walk along the road past the Tesco Express. Tania's street is just after this. Turn right into the street. It is on a gradual slope uphill on the left 3/4 of the way along. When catching the bus going back to Heathrow get it outside the fish and chip shop. When using the train station you can use your opal card. If you need to change to the circle or hammersmith lines you can change at White City but you need to walk out of the station to get to the next one that joins up.
The bedroom is quite warm I believe because the boiler is close by. There is nowhere to eat except on your lap and at times I found this awkward. Tania gives you lots of supplies of tea, coffee, UHT milk, biscuits and there are some soaps, creams, toothbrushes, etc for people who have forgotten to bring toiletries.
I believe that Tania does her best to make her visitors comfortable.
