It looks a nice caravan but a bit too heavy for my liking. I have to agree that the window at the bed head will make sitting up in bed uncomfortable and would prefer a blank wall even if it does reduce the light level.
We also have a 2015 model, mainly because my husband is claustrophobic and wanted an island bed and this was the only one that did not have wardrobes going up the side of it. And yes the split head end of the bed means it does not matter that there is a window there as you are not leaning on it you are reclining on your raised end of the bed. We have had some really lovely times away so far in our Adria and looking forward to loads more. Agree that it is one of the best ones out there (but perhaps I'm biased)!
By the way my husband received a pair of towing mirrors for responding to this review in the May edition of Practical Caravan.
