Our stay was very enjoyable and although we didn't see our hosts often, they were very hospitable and friendly. Breakfast in the morning was a very nice touch (which I had actually overlooked when booking!), and only being a one minute walk away from the tube station, the location is just perfect.
The room offers plenty of space for three people, although I imagine it might become a bit cramped if you stayed longer or have lots of huge luggage.
I would definitely recommend staying at Chris and Leroy's place if you are in London!
