My mother and I stayed here for 3 nights and we loved it so much, we didn't want to leave. :) The place is just as advertised in the photos, it's a spacious and comfortable home with one bedroom at the top of those lovely spiral stairs and one bedroom downstairs at ground level.
The kitchen was fully stocked and the living room had an immensely comfortable couch with a great view of the smart TV (which has Netflix access). Wifi connection was perfect as well.
As to the location, it's in a fantastic spot 2 mns away from the underground station and the District line which will take you easily into Paddington and the center of the city for sightseeing without transferring. Carla herself is super nice and responsive as well, so I fully recommend staying here if you're in London! You won't regret it.
