Very small cubicle (about 4 sq.m.) with just enough space for a mattress and a small cupboard but has amenities like air-conditioner in the cubicle and water heater in bathroom and is a short walk from MTR station and Bus Stand.
You need to be prepared to share a very small flat and a single bathroom-cum-toilet with 3-4 other people each staying in similar small cubicles with wooden partitions so you can hear what everybody is doing at all times.
Overall, good value for money at about HKD200 per night as accommodation in Hong Kong can be quite expensive.
