Roo and Rav are completely dedicated to giving their guests the best stay possible, at least as far as I can tell. They are thoughtful and considerate, and when they know something matters to you (for me it was a good workable desk), they make every effort to make sure you're happy. It's a wonderful place to stay.
Given that it's a big house with lots of guest rooms, they've done an amazing job of taking guests who are mature and considerate. I never thought that I'd be able to cope with sharing a small kitchen with 9 other people, but everyone was very careful about working around each other.
It's also worth noting that the house has its own vibe, which I found pretty awesome. It's colorful and interesting and decorated with things from all over the world -- in other words, not a minimalist neutral-colored freezer zone. That pretty much describes Roo and Rav, too ;-) But if you want minimal contact and minimal decor/color, it might not be to your taste.
Overall, a great place to stay. And I am confident in saying that this is the best room at the price within an hour of central London.
