My wife and I spent two nights here, in order to catch a flight more easily than travelling from the city. As others have commented, the hotel is right at the airport but without noise from the aircraft. It is also easy and relatively fast to travel from the airport terminal into the city using metro line 3.
All hotel staff were courteous and helpful. Our executive level room was spacious with a view to the extensive gardens at the front.
I don't know if it is a feature of all Pullmans but the large window allowing a view inside the bathroom from the bedroom was a bit different. It took us a while to figure out how to operate the electric blind for this window.
