Me and 5 friends stayed there for 4 days to visit Singapore. It wasn't really hard to find the apartment with the provided check-in file.
There were some little damages all over the apartment but since we only went there to sleep and swim it didn't change our experience in Singapore at all. The pool by the way was a highlight for us because especially at night you could see the whole skyline. Astonishing.
I would recommend this apartment for a group of max. 4 people otherwise someone has to sleep on the ground with a provided matrace and the other one on the couch.
