As repeatedly commented in other reviews, the host is really kind, accessible and sensitive to your needs. For example, our discussion about whether to buy a EZ-Link card (transportation card) was not necessary since the host provided them for free. Although you are sharing a house with your host, you will have your private bathroom, and the bedroom is really cozy.
The only con may be the distance from the downtown and distance to the subway station (a little bit more than 10 minutes walk, which may feel long during hot days in Singapore). However, this point can be an advantage as well; your apartment is located in a quite place, and we really enjoyed a local restaurant near our place! Liu will kindly tell you where to eat nearby if you ask him.
For us, bringing many bags, ride from/to the airport was really convenient. Note that the taxi fare in Singapore is not cheap - at least I felt that way compared to my country (South Korea).

Overall, this was my first Airbnb experience, and I liked it very much.
