I booked 2 nights for SGD 150 per night. When I checked in, I noticed that the walk-in rate was SGD 190 or 210, depending on the room. For this considerable sum of money, what do you get? A room that is just big enough to fit one bed. There is no proper table, no chair, and your luggage will just have to rest on the floor. There were some ants and fleas, although (I think) no bedbugs. Internet did not work when I was there. Someone also told me that the night before I checked in, a faulty fire alarm went off three times that night, roughly at one-hour intervals (1 AM, 2 AM, and 3 AM). As for the facilities, there are no facilities except for one washing machine. And the hallways are so narrow that two people would not be able to walk through at the same time without at least brushing shoulders. Also, the doors slam shut very loudly, and some rude mainland Chinese tourist woke me up at 1:20 AM by constantly knocking on the door of her tourist friends, in the room next to mine. (Also, these folks somehow felt that it was acceptable to stand in the doorways and shout between each other's rooms). In short, this felt more like a college dorm than a hotel.
The only reason that this miserable hole is able to charge such prices is that it is one of only four very small hotels near NUS or, in fact, anywhere on the West Coast of Singapore. But if you are willing to commute, then for the same money you can get a much better hotel (e.g. the Ibis at Bencoolen) for the same money. Or, you can have the same low quality elsewhere, but for much less money.
Another option is to stay in Johor Bahru, Malaysia, just across the water from Singapore, where you can get a 45-square-meter business suite for the same money as you would pay to stay in this college dorm of a hotel.
Again, stay away from this ridiculously overpriced, budget-quality (but certainly not "budget") rathole.
