We had an absolutely perfect five-night stay at Annie and Belinda's. They are such lovely people and we really felt at home in their house. The house is beautiful, full of interesting artwork and very clean. The bed was extremely comfortable and there was plenty of space for two people in the room. Every morning there was a fresh fruit salad and lots of muesli, toast and spreads for breakfast, which is something we really value as backpackers! The area is nice with a street nearby lined with shops, restaurants and a few pubs. It takes about an hour to get into the center of London by bus, but the transport is easy and we loved getting to see more of the city on the journey. Taking the bus/tube combo is quicker but we always chose the long bus route.
We have been using airbnb through 6 countries now and Annie and Belinda's has been our best stay. Highly recommended.
