Yes, the rooms are very, very small, but this is offset by many of the hotel's amenities including a super friendly and accommodating staff; a terrific location, just a block from the beach and close to shopping and many restaurants and bars; and a fresh and contemporary decor. We stayed here for just one night on our way to the keys but would definitely go back again.
Highlights of our visit included:
Cuban sandwiches at Puerta Suagaro, a Cuban diner on Collins Street that was recommended by the hotel
Custom cocktails (we told the bartender what we liked and he created something special for each of us) at the Rose Bar in the Delano Hotel; it was $46 for two cocktails including the tip but worth the experience. Note: if you do visit be sure to walk around the hotel including the pool--the decor is very hip
Renting bikes from the bike shop on 10th St (the least expensive bikes are oh so comfortable and it was just $10 for two hours) and riding over the Venetian Causeway into the city of Miami, which is about 10 miles round trip
