It is relatively basic, but has everything you need when exploring the city (A/C, wifi, free simple breakfast, locking storage, clean bathrooms and a bed).
Great location: far enough out of downtown to be quiet, close enough to get there easily.
Downtown Singapore is only a few stops away from the metro station that is a 3-5 minute walk from the hostel. Plenty of food options, a convenience store, and a community pool ($1/day) are within a block.
The very friendly, helpful staff is responsive and welcoming, and they keep the place very clean.
