u/ConversationJust7455

Hi. We are flying business class with BA on a Boeing 777-200 old ying/yang style and would like a window seat for my child and 2 others. Which seats are best? Row 1,2 or 4? Do all window seats actually have a window to look out of? Is row 1 too close to the toilet? I dont want to have a queue next to me of people waiting to use the toilet? TIA
