We stayed here for 3 days and had a really plesant stay, although the place is not in the city centre but it still reachable by MRT or Bus, nearest station is Haw Par Villa around 5 mins walking, if you a bit lazy to walk you can take bus for two stops to the station.
Anson was really helpful and communicative, amenities provided also very complete starting from bedroom, bathroom, and kitchen.
The place is not really big nor small, just the standard size and suitable for 4 persons, but we stayed with 6 persons and still acceptable unless you bring many luggage.
We would recommend this place.
