If you in your 20s, maybe you'll want the crowds and noise of surf-side; but this was quiet and clean and not crowded. Rather than busy restaurants, we opted for buffet foods and drinks from Whole Foods just a block away - and ate on our own dining table, with our own wine and great views from our balcony. Staff was wonderful - cleaning and desk staff of Camilla, Rob and Eddie.
Negative -- our freezer didn't work (iced up upon arrival and then melted onto some food; they sent up maintenance but couldn't seem to fix it; but they offered a discount which was nice and we didn't ask for) and the bathroom exhaust fan didn't seem to work -- again, during a five day stay they couldn't seem to fix it. but that was very minor.
Other than those two things -- we'd stay there again -- we didn't have a car (hard to find parking anywhere and expensive) but there was no need - we enjoyed the walks all around south beach area.
