Great hotel for more than 2 people and excellent location. My sister and her 3 children (ages 17, 14, 11), 4 of them were able to fit ok in the triple room. The bedding was good for this purpose.
The hotel's amenities is not top notch, bathroom vent is quite loud and the blinds played up a bit. But we weren't in the room much of the day so it served its purpose for sleeping only. At night it can be a bit noisy as there's a bar/club somewhere near the building. However, I didn't mind it because there's 3 different MRT around that makes it very easy to travel around Singapore.
Also, please be aware they do not have laundry facilities only laundry service. If you want to wash your own clothes I would recommend walking to Victoria Hotel, less than 10mins walk. They have a coin operating washing machine and dryer there that's open to the public.
