Stayed at the Park Hotel for a three night business trip. It was absolutely fine without being particularly special - but at the price I would happily recommend it.
Good points: early check-in (9am after overnight flight from London) and 2pm late check-out arranged with no problems and for no extra charge. Breakfast was fine and fairly priced at S$25. Location excellent if you're travelling by yourself as I was: perfect for an early-morning jog along the Singapore River and endless options of good bars & restaurants on your doorstep for people-watching over dinner.
Not so good points: no wi-fi in rooms (although free wi-fi in reception and by pool). Restaurant is quite small and gets crowded during breakfast. Sleep quality distinctly average due to poor noise insulation and low-quality pillows.
Service was always cheerful and efficient; in the round, this is a perfectly good option if you want something central and dependable.

Stayed here just for the night while in transit. Normally I would stay at the Swissotel nearby but I thought I would try something new. Overall the rooms were new, clean and in general quite nice however, I felt that the bed was not very comfortable. I could also clearly hear noise (toilet flushing, shower, talking, TV) from the room next door even though I did not have an adjoining room. On the upside, the room price was pretty good and I got an upgrade at check-in. Not sure if I would stay here again or not but if the price is right, I might give it a go again. The service staff seemed friendly as well and I did have room service and the food was actually quite good.

Never had an impression that this hotel can be that nice, stayed for 5 days , awesome view of clubbing hub Boat Quay, rooms are nice but a little small ( you can't expect more from Singapore) but lounge services, free drinks, free internet, spa was nice, staff friendly , cleanliness say 4 out of 5. A nice hotel.

Definitely yes for next trip.......

We stayed here for a week in January 2012. The hotel was lovely and clean and very comfortable with some very helpful staff especially Anand .
