Mint seating rows
 

The first row has more legroom in the bulkhead, I would choose that row.

There is a galley behind the last row that is used by employees and economy passengers using the restroom.

Thanks. I switched to row 1. I think I'd be more bothered by the bathroom door opening and closing on the wall behind me than passengers going to the front bathroom. It's making me a little nervous that seatguru calls row 1 an exit row (I have children under the age required for exit rows), but I didn't see an exit door in the pictures I found online.

I would go with row 1 in your situation.

I cannot see how row 1 could be considered an exit row. It is behind the bulkhead. For certainty, consider calling into Jet Blue and asking.

SeatGuru is often wrong and this is no exception.

Row 1 is most definitely not an Exit Row. It is a bulkhead with the forward door in front of it.

I'm not a fan of the Row 1 bulkhead on any aircraft so if it were me I'd go with Row 5. There is no galley behind Row 5. It's a refrigerator and cabinet with beverages and snacks for the taking. The doors are padded when they close.

I also don't think there is a difference between hearing the law door behind me or hearing the one in front of me. Also, there is likelihood people will queue up by your seat to enter the forward lav even though they are not supposed to. That would annoy me more than hearing a door open and close behind me.
