Enjoyed very much our stay with Kai. Kai and her partner are really nice people, always respond quickly, and have great attention to details. Great value for your money, especially if you are new comers to London/UK. You will be impressed by Kai's long emails, where you will definitely find a lot of useful tips and information. :-)
The location is also very convenient with walking distance to tube/trains and supermarkets.
Highly recommended!
