Taller half is 6' and all leg.

She had the joy of this seat (31 J) on a lhr-bos flight in March. It has one window, and you can look out it, but its not a comfortable angle for easy viewing.
A few caveats.
Everyone stands by the emergency exit and mingles to stretch and chat, so if you are into your personal space, this is not the seat for you.
If you don't enjoy small children having a look out the window on the emergency exit and listening to the parent talk to their child, then this is not the seat for you.
If you don't enjoy watching people go in and out of the toilets and wonder why they are taking so long, this is not the seat for you.
It is also incredibly loud, but that might be because we are 1. flying coach and don't have headphones 2. by the engines.
I book it all the time and hope that my upgrade clears, but ymmv.
