Hi, we had a great time in London ( the end of November 2022). As a tourist, we wanted to stay somewhere close to both a supermarket and the underground. It was only a 5/6 minute walk from the apartment to both parts. For us it took 20 minutes to walk to Kensington Palace and Heypark. Direct train from Heathrow to the apartment made it easy as well. It took approx. 50 minutes for us on the way to the airport since there was a somewhat longer stop in two stations. Allow plenty of time for the return. The standard of the apartment was good enough (possibility of simple cooking, pleasant on-call staff, ...). A few times we heard the ambulance driving by, so we thought ok it's safe to live here as the hospital is right around the corner.
missed having an electrical sockets in the bathroom. We will come back another time if we are going to London, thanks!
