Kim is a very lovely, helpful, kind and thoughtful host (Thanks for the New Year wine!). The flat is great for its location - we could get everywhere we wanted to with no effort. It's tiny but big enough for two adults for a few day stay. However, it's situated in a noisy area and it's by a busy street. Its equipment works fine but is rather old. It wasn't very clean as well, especially the bathroom should get a proper clean. There was no storage place whatsoever, which we found most annoying as we had to keep our clothes in the suitcase. There is a wardrobe but it's full of someone else's clothes, shoes, bags, underwear.
We do recommend the flat and the host, despite the few drawbacks we had a fantatic time in London.
