I can wholeheartedly recommend Suzanne and her place to any family (specially with kids) traveling to London. The place is lovely, very clean and well-kept, has a ton of amenities for kids and adults, very comfortable beds, a nice and renewed bathroom, the kitchen has everything you need to cook your meals, a nice fridge, washer and dryer, and the place is quite cozy. I also found the neighbourhood to be very quiet. (Since I am extremely noise sensitive, you can trust me on this one.)
On top of that comes Suzanne, who is very attentive and quick to respond. She goes beyond the extra mile to make you feel comfortable. We found the house very clean, she added her touch and a few pluses that made us very happy. There are very clear instructions for using the TVs and wifi. Any other question you have is quickly answered.
There is bus less than a block away, the lovely Springfield Park at 10 walking minutes, and Rectory Road station is about 5 minutes away, so you have options to go downtown.
As a family of four, we had a really great time there and will look no further next time we're in London.
