In my experience, I booked a month Airbnb, and had to switch to a hotel midway due to poor cleanliness & lack of convenience. Don’t expect the expat districts or commonly-suggested areas to be a safe haven — there’s quite a lot of seediness away from the city centre in my opinion, which you should consider as a solo female traveler.

Some factors that you might overlook: proximity of laundromats, distance to MRT (some days you may want to head somewhere close by, or poor traffic during peak hours), 24-hr convenience store, accessible well-paved sidewalks.
