I spent 6 days at Ruby's place during a regular business trip. I only met her a couple of times but she was very friendly and helpful and her communication was super clear (e.g., how to pick up the keys at a local shop as she wasn't around when I arrived). I found the house beautiful and very clean. My room was bright (adjustable with blinds if that's a problem) and quite large. The location is great with Overground stations nearby, which makes accessing other areas of London fairly easy.
