I stayed with Vivien and her daughter for four weeks while doing a placement in London. It's been a really good time and Vivien has been a lovely host. She's been so kind, sticking mý laundry in the dryer for me while I was still at work, letting me cook first when we were both about to have dinner and also giving me lots of life advice. Both Vivien and her daughter have always been up for a chat and are fun to be around, but definitely respect privacy and just let you do your own thing, which is a really good balance.
Other than that, Motthingham might not be the prettiest bit of London, but it has everything you need and the train station is really near by, so it's a really good place for anyone doing a placement in the city!
