It was really nice to stay in leah's house! she and her husband were so kind, we really enjoyed to stay!
But if you stay london for a short time you have to consider because it was pretty far from city. It took around 45-50mins to get piccadilly circus by bus, or we had to tranfer 2-3times by tube.
One thing that I was disappointed is the house cant block any noise, such as wood stairs or other rooms.
