I have been in The Residence - Etihad has been touring a full size mock-up around travel shows for the last year or so. It really is cramped - imagine living in the smallest apartment you can imagine! I got a feeling that it would get very claustraphobic over a long flight.
Give Etihad credit though. I was chatting to someone this week about his recent travels (he didn't know what I do, he was just a standard 'wealthy retired' gent) and he brought up The Residence up in conversation and even named it correctly. The PR works!
