Nice location, walking distance to ST. Paul cathedral (4min) and just a bit further and you are at Millennial bridge. We also walked all the way from Buckingham Palace to WestminsterAbby, London eye, River walk back to flat (15’500 steps in 🤩). Several coffee shops just downstairs of flat. Great location. I highly recommend to do Historic PUB tour by Liquid fluid history tours on TripAdvisor (and hopefully your tour guide is Dave)
