The staff is super attentive, polite, and ready to serve (it was because of their good attitude that make me come back). The check-in is done thoroughly with good pace, no rush at all. Bed quality is great for the price (plus, look the same as the pictures) yet public hygiene depends on guests. The staff often clean bathrooms and room floors feel clean. There're tables with chairs to sit for working, studying, or eating, but guests keep the cleanliness themselves. 
The hostel in a nice neighborhood with lots to discover around it. Walking to nearby MRT stations is approximately 10-15min and closest 7-Eleven is 5-min. Overally, I'm pleased with my stays at 7 Wonders and will use its service when I'm back to Singapore.
