Had a couple of nights here in last few weeks. Nice, modern hotel and very good for an airport hotel. I got a junior suite for first stay which had a large terrace that overlooked an office building, so a bit odd. Second stay got a room in the curved part that had a very small window and a weird dark area with a single chair. Both rooms were fine but a bit strange.
Rooftop is fun but we were there on a weekend and its clear many locals come in to use the pool. It was very busy and also very clear these were not people overnighting before a flight. Kind of like a slightly sleazy W scene.
This said, would happily stay again, location cannot be beaten for after/before a flight and very nice staff.
