I was on the A321neo yesterday and can confirm that for those of us confined to Euro Traveller, rows 16 and rows 27 are the ones to go for. Both have 6 seats. Row 16 is your standard type of exit row with a bit of extra leg room, and has a proper window, akin to row 12 on the A320. Note that unlike the A320 there is only one mid-cabin exit row.
Row 27 has infinite legroom. A and F face the rear-facing crew seats in row 26, with the door in between. This means that there is no window, though A and F can look backwards and see a little out of the row 28 window. A & F also have a moveable armrest on the fuselage side, which gives you a little extra room. BC and DE are fixed and offer no flexibility. Row 26 only has BC and DE in order to accommodate the aforementioned crew seats, but the seat plan (32Q) could fool you into thinking that these were exit row seats. They are not, and have standard leg room. Obviously B and E have only have two neighbours for a very short time, most of the flight you will have a little extra space in those seats, or at least the impression of it.
As far as I could tell, none of the seats reclined in row 27 where I was. The seats are the very basic slimline ones. I would imagine they would be OK for a 2 hour flight. I was inbound from Larnaca and found myself getting a dead leg in the latter half of the flight so I had to go for a wander. There was power in row 27.
The safety card (issue 1 A321neo) is a little odd. The outside cover shows the aircraft with sharklets, whereas the inside pages with the cutaways show the aircraft instead with winglets. It also seems to suggest that there are two over-wing exits next to each other like the A320 - it could be that someone has tried to reuse that schematic.
The aircraft also has the hidden in plain sight lavatory in the rear galley, with the door disguised as a crew seat. No matter how many times I see this I am always fooled and end up waiting when in fact it is empty.
