I spent one night at this flat. Liz is very friendly and I had all the amenities that I expected. The location is right on Hyde Park so very convenient for central London. This room represents great value for money for such a superb location. I would stay here again.
The only issue I had was with the airbnb app itself which sent me to the wrong location (though within 10 minutes walk) so I recommend double-checking against the address, rather than the airbnb pin-drop.
