Here's my post on Google Review:
What is good? Grand Park City Hall is the best value for money in this locale. I booked a Deluxe Twin Room for 2 nights. The room is slightly larger than most newer hotels, which charge at least $100 more without breakfast. My comes with breakfast, which has a sumptuous spread given such a small dining area.
As I am a Singaporean, I of course know my way around. The National Gallery, Marina Bay, Merlion Lion Park, and Suntec are all accessible, making it even more convenient with the underground link. It is unfortunate that the hotel is not linked to the underpass network. Perhaps if the owner could explore that with URA/ LTA, the City Hall Mall would be more appealing. Its also rather unfortunate that the commercial portion is largely vacant since the last revamp.
I read some of the comments related to the 1/5 post. Most seem to relate to service quality. At times, if we ask nicely ourselves, we could be treated better.
