For the price, it’s worth it! Aljunied MRT is more of a 12mins walk using pedestrian crossing and not a 6min walk (unless you jaywalk) but overall still a great location with nearby food restaurants and hawker stalls. There is a mall one stop away at Paya Lebar (PLQ Mall) for your shopping needs - great japanese restaurants there, too.
The rooms itself are generally clean, just a little bit dusty. The trashcans in the toilet ought to be thrown out regularly and some of the door locks are quite flimsy.
The garden space is quite pretty, great for photos.
I would for sure book this place again if I ever visit Singapore next time.
