Rich's flat is in a superlative location - 3 minutes (if you're a slow walker) to Paddington and 3 minutes to Hyde Park and 3 minutes to the Lancaster tube stop.
The value for the money is excellent.
WiFi is fast and easy.
Kitchen is superb - I'm an excellent cook and if we had stayed longer, would have really enjoyed cooking there.
Two comments to be aware of:
1- there is ongoing work in/outside the building. The carpet is torn up, there is scaffolding everywhere, and the painters are at it. That will all clear up, but I recommended to Rich that he add a note to that effect (i.e. work complete, everything is now wonderful)
2-It's five flights up a narrow set of stairs with no elevator. If you are not fit and/or are planning on bringing heavy luggage, be aware!
Having said all that, it's great value in a prime location.
