Words can't even describe how incredible the stay at Kathleen's house was. But, I will try to give it a shot.
I stayed for over a month for my summer exchange at SMU. So let me start with the localization, the room...
The house is located in a quiet neighbourhood, 5 minutes walk max to the MRT (Singaporean subway) at the station Tampines West, which is so convenient since you can go Downtown in 20 minutes max. It's also near the Changi Airport, so you can go there by direct bus, MRT or a Grab at 10 SGD in 10 minutes max. However, Kathleen kindly takes you from the airport when you arrive and proposes to get you there when you want to go.
Besides, if you are a runner or you want to cycle (they can lend you a bike), there is a nice spot called Bedok Reservoir at one station from Tampines West by MRT or 10 minutes max by bike.
Within 1 minute walk you can find food courts where you can eat, 7eleven... I advise you to go to the Tampines Mall and Century Square, 2 shopping malls (10 to 15 minutes walk, or 5 minutes by bike) where you can find gyms, swimming pools, food courts, western food (McDonald's, Starbucks...).
Regarding the room, it's super clean and confortable with a good bed, mattress, air conditioning, private bathroom, you can also do your laundry...
But the best part is living with this nice family. Coming back to Kathleen's house from school, or from travelling around always felt like coming back home. My trip in Singapore wouldn't have been as a great experience as it was without Yvonne and her parents warm family atmosphere.
I will miss you guys and I can't imagine coming back in Singapore anywhere than in your home.
