My partner and I spent a very enjoyable week at Helen's flat. Helen was an amazing host, arranging to meet us early in the morning after our 30 hour flight, and stocking the fridge/cupboard with some much appreciated items. The flat has plenty of space for two, the appliances all work as described and the bed is very comfortable. The location is amazing, allowing you to walk to pretty much anywhere of interest in London within 30 minutes. We'd love to visit again some time.
