It's been a while since I've looked, but no IHG property is accessible to the airport -- by easy public transport, or free shuttles. I saw some nasty complaints about IHG-brand "airport" hotels that aren't.

I once stayed at one of the IHG "airport area" properties (Hospital Infata) on a points break sale, but I knew what I was getting into. That is a nice hotel, but a LONG metro ride to an industrial neighborhood. Fortunately, there was a decent restaurant bar nearby.
