We enjoyed our stay at Jonathan's flat. The view from the 9th floor over the rooftops of London is beautiful. The location was perfect for exploring the city. We were able to walk or take the Circle Line (without transferring trains) to all of the main London attractions. Being right across the street from a grocery store and a food shop was convenient, especially since Jonathan provided all the basics for cooking in.
Bedrooms and living spaces are well appointed with all the essentials. The mattresses were firm.
Our one difficulty was experiencing a London heat wave. We're not used to 90+ degrees without AC. But Jonathan helped us buy fans for the bedrooms the the flat gets a good cross breeze to cool down at night. We felt safe even with all the windows open.
