I suppose the aft (row 3 I think despite the seat accross the aisle from it being row 4!) most E/F seats in the forward club section would be your best bet (less distance from the door and toilets and no passenger's legs to climb over) but it would still be quite difficult as you could only get near with the aircraft chair but not next to the seat as with the aisle seats. Not sure what (if there is any) the policy might be on carry on passengers in these seats though?
