Cube hostel is very private even though it is shared space for sleeping. I had a really good night sleep the five days I stayed there, and there’s a real culture of respect, and quiet in the rooms. I am a girl traveller and had no issues whatsoever, even though it’s mixed (I was concerned beforehand.). The place is really well located, in a very chic place of Singapore, and was very easy to find and get to. You just say “Arab Street” or “Kampong Glam” and any taxi will find the way. I can say the staff is amazingly servicial and are very concerned with your needs. Amazing Mediterranean food is available at just 10 steps out of the hostel, and if you want a beer in a nice indie street, you’re about 20mts away from great places.
The bathrooms could probably be cleaner, even though it’s expected in a hostel especially in the mornings when everyone showers. However, there was nothing too dirty, or unpleasant. Would definitely come back!
