Our stay at Jean's house was lovely. She was incredibly friendly, and always up for a chat when we came in from seeing the city. She provided a cooked breakfast every morning and offered suggestions for things to see. The bed was very comfortable, and house was clean with lots of cute decor :) Wansted is a bit outside the city centre, but Jean's house is a five minute walk to the central line, which will take you into the city quickly. And the area near the station is nice for food and drinks on your way back. Would definitely recommend Jean's for a comfortable stay in London.
