We stayed at the Pan Pacific in Singapore for 1 week (you must have a min of 7 nights booked) and overall it was lovely. The decor is high-end and modern with great art in all areas of the hotel. Our bed was very comfortable and was a nice retreat from all the action on Orchard Rd. My biggest complaint was the construction, and not just the noise, but the privacy factor. There is a large mall and parking structure being built just inches from the hotel itself and it is swarming with workers who would like nothing more than to sneak a peek whether you are in the pool, working out in the gym or relaxing in the soaking pool. I even caught one taking a picture of me with his camera phone while I relaxed by the pool!
Other than the peeping-toms, I don't have much else to negatively critique. The breakfast was lovely in the mornings, the front desk was very helpful (especially when our washer/dryer broke down), the location is ideal (Somerset MRT is directly under the building) and the attached restaurants are amazing.
Going to Singapore was an exotic adventure for me, so the Pan Pacific was a wonderful place to call home during my visit. Once the construction is complete, I would highly recommend this hotel to anyone visiting Singapore for business or leisure.
