"jein".
i would check the airplane for your flight first, then check the your seat on expert flyer.
going on an A359 e.g. in a row with 3 seats for you alone is still an enjoyable way of flying,
in the end it sould simply be a question if you want to spend the extra money.for biz. ~ 600 GBP for only one sector (!) is definitely none of their better offers.
