We enjoyed staying at your flat. The location was great with it's proximity to Marble Arch tube station and a short walk to Paddington Station and the Heathrow express. Very clean and great view from rooftop balcony. We were disappointed with the lack of aggressiveness shown to fix the water issues. The hallway shower had some definite issues. We knew how to operate and it wasn't operating correctly and shutting off mid shower. It made the hall bathroom unusable for showering. When asked halfway through our stay for you to fix it, you responded with asking for a follow up video and when we will be home for maintenance, inferring that we need to alter our plans in London to be around to receive a maintenance tech to come investigate. A suggestion would be to take our word for it and send a plumber straight away. The no hot water issue arose on the next day. That was fixed in a timely manner, but the hallway shower issue was never fixed during our stay rendering one of the bathrooms unusable for showers for 6 people. Unsatisfactory for paying that much for a flat in London.
