I find that you can roughly categorise Singapore hotels into 3 categories:
1. The 5 star luxury hotel
2. The 4 star very nice hotel
3. The hostel type rooms which generally have no windows.
When my missus went over for a training course last year, the company had originally booked her in the 3rd type......much like Katherine's room but with stains on the sheets. She stayed there a grand total of 2 hours before grabbing a taxi for where my sister lives and stayed there for the rest of the training.
