In the reconfigured A321, there are 4 rows of first, followed by 4 rows of coach (rows 5 to 8), then the second doors. The 4 rows of coach are 3 x 3. The closet is gone. So your 7F is a window seat.
I'm not sure if they all have been reconfigured, they have been working on it since April. If you get one that's not, they will move you back.
