Woolwich 2bed flat - new flat came to market priced so much lower than neighbours? a gem or a catch?

Have been looking at Woolwich 2bed flats for a while and loved this development when i went to see it in person

in exact same building, there are:

- 350k for 2 bed / 1 bath - exactly the same but i actually like the decor of this 325k better and no neighbours!

- 375k for 2 bed / 2 bath (50k+ for 1 more bathrom doesnt make sense??)

- 2x 400k for 2 bed / 2 bath

- 425k for 2 bed / 2bath

and the building next door is 1x 395k and 2x 400k flats for 2 bed 1 bath
