hi,
it depends whether u are driving or taking the MRT. Going from one place to another doesn't take long. AISS is at Lorong Chuan n there's a
condo near the station. The distance between AISS n UWC East, taking the MRT, is not that far. I think about 3-4 stations apart.
Depending on what type of accomodation u are looking at, I think staying at Serangoon or Ang Mo Kio is the best.
PM/ email me if u are not sure.
*there's bus services for AISS for students
Please be kind to animals..
