Helena and Vincent are very friendly, inspiring and open minded people. They create a welcoming atmosphere. It was nice talking to them. I had some health problems (headaches /migraine). So I could not go out and explore London as much as I had planned. I spend more time in bed than I had planned. I was worrying that spending a lot of time in bed could disturb them. But they seemed to be okay with me leaving the house always after noon. They are great! I like them and what they told me about themselves and their work.
