I stayed at the Cadet in May 2008 while in town for a few days. Like many of you, I spent a lot of time researching hotels in Miami and was shocked at the prices! I decided to give the Cadet a try, given all the positive ratings here.
The hotel itself is nice: tasteful decor, and polite (if not effusive) staff. The location is great - just 1-2 blocks from the main thoroughfares, and walkable just about everywhere.
Just keep in mind that this is Miami, and the rooms are small. This is standard for most of the older hotels in Miami Beach. If you expect to do a lot of lounging in your room, then I wouldn't recommend this place. But if you just need a comfortable, clean place to spend the night, Cadet does the trick.
Also, I booked directly with the hotel by calling them. I looked on different websites, which suggested that the hotel was full on the nights we were going to be there. But when I called, they had rooms available.
