Wouldn't stay again
Stayed here for a conference, food ok, not worth the cost. Room very tired and basic. Only got 4 hours sleep as from about 4 am constant doors slamming from the flight attendants. (Large number of flight attendants, pilots etc stay here).
I would suggest that as it's such a large hotel that they put flight staff and other guests separate. We were at the furthest point (approx 10 min walk) the whole wing of hotel was taken over by flight staff, which is fair enough but when booking make sure you stipulate you don't want this. I did not know in advance and when I mentioned it at reception they said it was the only room available! Would NOT come back especially as I stayed previous in the Novotel over the road, for same price and it's much much nicer.
