Positive:
The location is excellent. The Airbnb is located about 10 mins walk from the MRT station / SOGO shopping mall. There were also 7-11 and food stalls within the vicinity.
The host typically replies within the day, and very often within a few hours.
Lots of baby amenities were provided, including baby soap, stroller, bath tub...etc.
Negative:
Lack of heater. I stayed here in December and the place could feel pretty cold at night. Thick blankets were provided, but were unsuitable for use with little babies. Families travelling with babies should be aware of this limitation.
The playpen provided had an uneven and rather hard "mattress" (which really is just a play mat). The "mattress" was the foldable type had gaps in between which felt uncomfortable. The play mat also didn't fill up the playpen completely.
I stayed for a total of 7 nights and there was only one cleaning provided. Furthermore I was requested to be away from 11 am to 4 pm (5 hours in total) on the cleaning day. This is quite inconvenient for families with babies that need to take naps during that time.
The apartment could not be latched. The security of the apartment was totally reliant on a digital lock on the gate. The main door couldn't be locked at all. While nothing happened, families might feel safer if they could latch the door at night.
The check out time is rather strict. The check out time is 11 am, but my airport transfer was scheduled for 1 pm. I requested to either have a late checkout or at least be allowed to leave my luggage in the apartment. However the host only allowed me to have a slightly later checkout at 1130 am. Families with young children (and lots of luggage) need to be careful of this limitation.
The building is rather old and looks run down. The fire escape staircase doubled up as the rubbish dump which felt quite hazardous. In fact on our very first day, there were bulky items blocking up the staircase.
The photos look much much better than the actual apartment. The stated amenities were indeed provided, but everything looked older and well used.
