I stayed at the Mandarin Oriental Miami for four nights in February and had a wonderful experience from the time I arrived until the time I left. The hotel was beautiful and service was superior. Rooms were large and beautifully decorated. You will feel instantly relaxed as soon as you walk in. The large marble bathroom featured a large shower, large soaking tub, and separate toilet area. The balcony offers wonderful views and adds to the serene experience.
The pool area is very relaxing and offers a wonderful view of the bay. The man-made beach is also a wonderful relaxing area.
Every element of the customer service was exceptional. If I could give the service more than five stars, I would. I was regularly greeted by name as I entered and exited the hotel. The concierge service was extremely helpful as well, recommending fantastic dinner spots.
The food at the hotel was also delicious. For breakfast, I visited the coffee stand which offers an assortment of bagels, pastries, and other similar selections. For lunch, I ate at the restaurant by the pool, which offers an assortment of sushi, sandwiches, salads, and burgers. For dinner, I visited Azul, which offers delicious Asian Fusion cuisine. I highly recommend ordering the key lime pie for dessert.
One thing to keep in mind is that South Beach/Miami Beach is a little bit far from the hotel. You will need to take a taxi that will take about 20-30 minutes (depending on traffic) and will cost about $30. That being said, the hotel is in a serene location on Brickell Bay - very private, safe, and amazing views of downtown Miami and the ocean.
I highly recommend the Mandarin Oriental Miami, and am looking forward to staying there again the next time I am in town.
