I stayed six months with Gill and Graham and I can't imagine better hosts. The room is very cosy and perfect located. Just a few min walk is Little Venice and a 10ish min walk is Paddington station. The tube (bakerloo line) and many Busses are also very close by. In the fact of the central location the room is quite and you can space out from the big city London. The beautiful big garden is one nice place to back down. The neighborhood is very friendly and properly british. I got to know of british culture as Gill and Graham were very endeavoured to introduce me in everything. Living with Gill and Graham is very easy and pleasant. We cooked together, took action and laughed a lot. Last but not least the black cat Django is a character you shouldn't miss.
I really can recommend this room for long term stayers but even for a short term you will feel being at home. Gill and Graham were a pleasure to stay with!
