We stayed five nights and six days and booked a harbour room through their Internet. We also booked airport pick up, used their concierge, exchanged money, checked out their gym, ate at their restaurant and used room service and dry cleaning/laundry.
1. Airport pick up: the driver was on time holding a paper printed with the guest's name outside the baggage area. We got the exact car that we wanted and it had two cold bottles of water and cold towels ready.
2. Check in: we were greeted right after we got out of the car and escorted to the room. Tea and fresh fruit was waiting. Our room was on the 20th floor with harborview. Luggage arrived quickly.
3. Room: floor to ceiling windows, extra amenities like emergency flashlight, umbrella, two robes, two slippers, complimentary bottled water daily, Molton brown toiletries, bath salts in tub, loofa scrub, some office supplies (staples, hilighter) room, night light. High tech lighting controls as well as privacy indicator. There was an indirect view from the bathroom due to the glass wall. Two toilet paper racks in bathroom, three phones (one in bathroom) a tub and a shower
and one sink.
3. Concierge: excellent service and we used them to book a few
tours (malacca was a good one but tiring, raffles tiffin, night safari
riverboat, flyer). Money exchange was a breeze with them
4. Dryclean: they found a button missing and insisted on paying for
it. Price is high but expected. They returned our clothes the same day despite dropping it off at lunch. Laundry was neatly folded in a basket with a flower on top. Clothes were in plastic (not wires)
hangers in the closet.
5. Room service: brought a table with food kept in a warmer. Arrived
in 20 minutes and picked in five. Great selection of Indian,American
local cuisine.
6. Location: across from the esplanade, attached to marina mall,
walking distance to merlion, singapore river but we used cabs to go everywhere which was cheap. It was too hot to walk.
7. Food at The melt. Get the breakfast rate or it could be pretty
pricey. We came in 10 min before closing and they extended the
closing time.
8. Gym with cold towels water and techno equipment. Overlooking
pool Spotless.
9.Customer service was their strongest asset. Always with a smile
and anticipated our every need. No worries was their motto.
Concierge walked you out after calling a cab. Housekeeping was
excellent with attention to details. Change in throwpillows during
turndown Amazing. Everyone knew our names.
Minor quirks (which might just be me): wifi is not free,(30 sgd/day
or 20/12 hrs 15/ 6 hrs etc ) it is free if you booked the club lounge. My pet peeve was that the hair dryer was attached. With that view I would have loved to move around. No flat screen tv but with surround speakers.

Overall the best experience we've had in Singapore due to both the
view and customer service We have tried the ritz and the four
seasons (comparable customer service) but mo has both. We would
definitely return.
Suggest: try Singapore flyer, night safari, riverboat 30 min trip, malacca
only if you have time, sentosa cable car, images museum, chili crab with
man toux bread (east coast seafood).

Our second stay at MO, Sing in as many years. They have never let us down. We booked a City Suite through Amex and were upgraded to a Harbour View Suite. Spent 7 nights there.

The staff could not be nicer... right from the Bellboys to the Room Service folks.

We were travelling with my 2yr old daughter. She was virtually adopted by the folks working at Melt - the fabulous breakfast restaurant.

We did a lot of room service for my daughter - dinner time - and they would make us off-the-menu items. We used their excellent baby sitting services too - hotel staff.

Due to the National Day Parade it was a bit noisy with all the practicing going on but we didn't mind. At their rehersal my daughter got to enjoy the spectacle from our balcony - including some nice fireworks.

This is a fabulous hotel - don't think twice about booking to stay here.

From the outside the Mandarin Oriental looks rather unimaginative, but as soon as you step inside you are transported to hotel nirvana. The lobby is spectacular, albeit somewhat dark, with striking artwork and a large reception area that easily accommodates large numbers of guests arriving simultaneously. We were greeted by lovely reception staff, and were upgraded to a suite and provided with late checkout til 6pm. Upon booking we had mentioned that we were traveling for our anniversary, so the hotel saw fit to put us up in a fantastic room. In less than ten minutes we were riding one of the panoramic lifts in the atrium up to our room.

Although we have often stayed in hotel suites, this particular one was no mere hotel room, but rather a full apartment in itself, with a separate dining area, kitchen, living room, and bedroom. The decor throughout was impeccable, and the service continued to raise the bar. Perfectly timed with our arrival, our bags came split seconds later, followed by a complimentary fruit and tea tray. The bed was one of the most comfortable ones I have ever had the pleasure to sleep in, with a choice of pillows that satisfied even a fussy sleeper like myself.

I feel that one of the hallmarks of truly great hotels is invisible service, and staff that can truly anticipate your needs. Housekeeping managed to slip in and out of our suite unnoticed, and the turn down service was perfectly timed to coincide with our dinner outings. The concierge was extremely helpful, and was able to provide suggestions that covered everything from entertainment to dining and shopping. The service throughout was simply outstanding - genuinely hospitable, knowledgeable, and efficient.

The hotel is located a little bit on the periphery of the more happening spots, but taxis are fairly cheap, and are a widely used means of transportation. The MRT is also extremely efficient, but you will have to walk a bit to the nearest station, and Singapore is not very pedestrian friendly in all areas. As a result, we ended up hopping in a taxi every time we stepped out of the hotel.

I would absolutely recommend this hotel to people who want to experience hotels as they should be - supremely comfortable, with friendly and efficient staff, immaculate service, and beautiful interiors.

As a sightseer this hotel leaves a lot for desiring. We found Singapore customer service in general was greatly lacking but we expected better at the Mandarin Oriental....and were disappointed. Customer service at the concierge/front desk was very spotty. We actually had a concierge tell us to walk several blocks out of our way to do a money exchange because he was too busy chatting with his female coworkers. Lobby not that impressive but rooms decorated nice enough. You can tell the bathrooms are a bit old but still nice. It's a fine hotel for business trips but not very romantic or leisurely. Good access to the malls by the harborside and once you get a hang of the thoroughways through the malls, you can access the subway (MRT) almost without going outside - although it's still a good 10 min walk. We took advantage of the food court directly across the street from the hotel which was nice. Expect to do a lot of walking if you're sightseeing Singapore and don't expect great customer service even at the nicer malls.
