Everything was perfect - from the welcome at the train station, during the wonderful hospitality throughout my stay, until the departure, again at the train station! Lily is one of these amazing people who morphs from host to friend with such an ease that it leaves you feeling as if you've always known them. House is warm and welcoming, my own living quarters were equipped with a comfy bed and nice, well stocked bathroom, surrounding areas are full of parks and walking paths, and there is a little friendly frutteria right around the corner beside the convenience store and wee fab Chinese takeaway. Train takes you to Waterloo in half an hour and a bus to Richmond Green and fabulous Prince's Head in about the same time (a tad more, perhaps).
In short - I had a wonderful experience and can heartily recommend it to all!
