Isabel is very courteous and kind. She came to the airport to pick me up which was a very welcome touch. The airport was extremely crowded and not very clear signage. Also, I don't speak Portuguese, so having someone meet you at the airport is a reassurance. Isabel doesn't speak English very well, but this was not an issue at all and we were still able to communicate. It helps to know French if you don't speak Portuguese. Her French is fantastic and she was patient enough to hear me stammer through my basic high school French.
The place is extremely clean, Isabel is very tidy. Location is literally no more than a 10 minute walk from Terminal 1, but if you're leaving from T2, book some more time for the airport shuttle.
