Pros
Location: 2 bus stops from the airport
Clean, average size, en suite bathroom (you feel like in a hotel)
Sufficient Wi fi (varies from 5 to 25 Mbit/s)
Cold air conditioning
Tea and coffee facilities in the room
Good "quality to price" ratio for Singapore

Cons:
Location: not central. 10min by bus +30min by train to the city center
Like hotel: you have to fill a check-in form upon arrival. No interaction with the host (only with the cleaning lady who also lives in the house). The fridge is in your room so it shows you are not supposed to use kitchen facilities.
Air con blows cold air right through one side of the bed so one might catch flue during the night.
