I stayed here for 4 nights for the Miami Boat Show. It was nice to have such a quick trip from the airport to our hotel. The shuttle got here in just 5 minutes or so.
Our crew had rented a couple minivans to transport us all over to the Miami Convention Center and Seaisle Marina. The hotel is right off the highway, so it was easy to hop on and off, to get to our destinations quickly (unless we mis-timed rush hour).
The room was comfortable (I was in a 2 bedroom suite). The kitchenette was a nice feature, and the maid service made sure that our dishes were cleaned in the dishwasher. The free Wifi was speedy and reliable.
The Residence Inn is on a Mariott campus which has 3 hotels, so there were plenty of accommodations on-site. The campus was gated in for safety, though I wouldn't have felt unsafe without it.
This hotel had free hot breakfast, with entree features that changed daily. It also had free suppers 2 or 3 times a week in which you could come down and socialize and network...this is great for business travelers.
