We stayed for two weeks, in a studio apt with living room/separate bedroom (9th flr). It's very well equipped and comfortable, with a mini kitchen, full sized fridge and washing machine/dryer. Overall location is good - you can walk to sim lim square & bugis junction.
BUT the immediate vicinity has nothing except indian food. The mall attached to the hotel has nothing interesting: only saris, byriani meals and a giant math tuition center. There is ONE starbucks downstairs, and that's it. The hawker center (Tekka Market) across has 75% indian food. OK if you're into that. There's NO 24hr 7-elevens nearby, but there is Valuestore across the street, which closes at 9pm.
We applied for parking next door, as we rented a car. Entering/exiting the parking needs patience: drive through backroads, make several turns, avoid jaywalking pedestrians, before getting on the main road. Once we got trapped 30mins in a long line of cars struggling getting out to the main road.
The service is NOT great. Whenever we asked for something from the front desk, like an extra drinking glass or toilet paper, it never happened, or turns up a few days later if they remembered. It's not fantastic.
Free grab-n-go breakfast is awesome, but we preferred eating at the rochor hawker center nearby.
One more thing: the room seemed haunted. My wife kept having the same nightmares about 2 characters in the room night after night. We thought that was very odd. She never has nightmares, only in this hotel.
