The communication was great. The location super for a pleasant visit to this fantastic city with easy walking distance to Paddington Station or Victoria Gate bus stop. The street outside the apartment can be a bit noisy in the evening but it didn't keep any of my family from having a good night's sleep. Hyde Park and Kensington Gardens are also within easy walking distance. The apartment is situated just outside the London congestion charge area and there are places close by where a parking space can by rented. Check the JustPark app.
Our apartment was on the second floor. The stairs may be a little steep for some and there are no lifts. It wasn't a problem for us but may be a concern if you have mobility issues.
All in all we have a great time with the apartment serving as a super base to explore London from. Check was a breeze and communication was spot on.
