If you hesitate booking this place I can only advice you to stop doing that, just book your next stay in London at Annie's and Belinda's place IMMEDIATELY!
There's not too much to add to the already existing reviews.
Annie and Belinda took really good care of my friend and me. It started with a free upgrade and then being great to communicate to. Our flight was delayed but dealing with our late arrival was no problem at all, we were welcomed with open arms and felt comfortable from the very beginning.
Every morning one of the two gals (and two lovely Dachshunds as well!) would welcome us with an A+++ breakfast, they even took care of my non dairy needs. Fresh fruits, bread and the best muesli I've ever head were a really great nutritional foundation for exploring London all day :)
These two (or four) are extraordinary hosts that will make you feel like being home, they showed so much interest in us and our plans and took really care of us, plus you won't only have a wonderful place to stay at, you will also meet to wonderful people with great recommendations and wonderful stories to tell you.
I can't wait to come back!
