We spent two nights at the Hyatt Summerfield Suites Miami Airport in april 2010. The suite was large : one spacious room with sofa bed and flat screen and a kitchen (with big fridge, stove with oven, micro-wave, dishwasher, toaster), a bedroom with king size bed and another flat screen and a bathroom with one part with bathtub combo and toilet and another one with washbowl and wardrobe.
The hotel has a pool with pretty gardens and offers a complimentary hot breakfast buffet and a complimentary social hour with soda, beer, dips...
We were very satisfied with the hotel services, the hotel shuttle picked us up at the airport when we arrived and drove us to our rental car location the next day. We asked by fax to get the sofa bed ready for our son as our flight arrived late, it was done.
