We stayed over at T5 before flying onwards to our holiday. On check-in the staff had noted my partner's birthday and greeted us with an upgrade to a Club Room. The service and experience just got better from there.
Very comfortable, large room with everything looking like new. How on earth they make soundproofing like this I have no idea, but the room overlooked the end of the runway and you couldn't hear a thing when the jets took off.
The club experience was lovely. We had missed Canape's (which finish at 8pm), however our host Jair offered to make us some hot and cold ones from the kitchen. What a bloke.
Location is excellent as the hotel is connected to the terminal. Highly recommended before or after a flight from T5.
