I stayed with family at Sandy's apartment for a month. She is a great landlady and here's why: we had some minor maintenance issues (A/C and drainage) and she addressed them promptly to the best of her abilities. We mentioned that it would have been nice to have a couple extra items (such as a garbage can for each room) and she had them delivered within a day or so. Furthermore, Sandy is fluent in both English and Mandarin, which was super helpful as my fluency in Mandarin isn't great.
In terms of the apartment, overall, everything is super clean. The washroom doesn't have a lot of space and it becomes warm rather quickly (so it feels a little stuffy), but if you leave the door open when not in use, then it's perfectly fine. The showerhead is awesome, so showering is super relaxing. There were only two of us living here, but I wouldn't recommend more than three people simply because the toilet and shower are in the same room, so washroom-waiting-times might be rather long. In terms of the kitchenette, Sandy provides some pots and pans so cooking isn't an issue. She also provides a mini toaster oven and a microwave, so those are nice as well. There is a washing machine available and several hangers to dry your clothes outside, so that makes doing your laundry very convenient.
Regarding the bedrooms, please note that there won't be too much privacy available. The two bedrooms are "stacked" on top of each other so one is lofted above the lower bedroom. The lower bedroom has a door, but the bedroom above does not, so you can see directly into the entire room from the kitchen, especially if you just stand on the staircase towards the upper bedroom.
The location is perfect, between two MRT stations. There are lots of food/restaurant options available around the apartment, and there's a grocery store within a 5-minute walk.
While there, a building across the street was under construction, so during business hours, you can hear the banging and the jack hammering quite clearly. I'd wake up around 8AM because of a worker shouting at his coworkers on-site. The noise isn't constant, but you'll definitely notice it when there's some drilling going on. If you're out on an adventure most of the day, then the noise isn't an issue because the workers are gone around dinner time (5:30pm ish, probably 6pm at the latest).
Ultimately, Sandy's apartment is great and is in a very good location. I would highly recommend it for a small group of friends or a small family.
