I would rate Kein’s place as moderate. The bed is comfortable, the air conditioner is good and the kitchen is reasonably equipped as long as you’re not doing proper cooking (only one burner and one small pot). But check in was difficult because no one picked up the intercom for about half an hour and i had arrived at night so I was worried I wouldn’t be able to get in. Some small touches would make the place more comfortable, such as hand soap and a hand towel. Overall it was okay but pretty expensive for what it was (but Singapore is expensive so maybe not out of line with other places).
