I have stayed at the Conrad in Miami several times from 2005-2008, but this was my first time back in a few years. I have always preferred it to the Four Seasons across the street because it has a greater sense of style (although the pool at the Four Seasons is superior).
On the positive side, the hotel remains clean and modern and is often the best value on its stretch of Brickell. However, the setup of the lobby remains irritating - although is very common for these shared office/residential/hotel buildings. Unfortunately, I also learned the hard way that the walls were thinner than I imagined by staying door to a crying baby.
Nonetheless, I would be inclined to return to the Conrad on my next work trip to Miami for its relative value and style.
