We very much enjoyed our stay. The rooms were well-appointed, and the kitchen was stocked with all we needed to cook during times we didn't want to go out.
The location was great for us, in a walkable neighborhood, close to the grocery, and importantly close to the tube and buses. It was easy to navigate the full city from our location. Plus, the flat was in good proximity to Portobello Road shops, restaurants and entertainment.
We had a few minor issues, but the hosts were incredibly responsive and attentive. I would highly recommend.
