Frosty reception when we checked in and experience with different staff ranging from indifferent to very helpful.
Also be aware that Accor Plus membership is not recognised if you book via AirBNB.
The picture of the room is very misleading as to the room provided (albeit the size/room is not guaranteed as per the notes on the booking).
Offsetting this is that the savings using AirBNB were significant, with the location and proximity to Paddington Station and Hyde Park being a big plus.
On balance we would stay again.
