Stayed at Habitat Residence for one night having arrived off a flight and going on a cruise the next day. It was absolutely ideal for us (4 adults). Huge 2 bedroom apartment with a massive amount of closet space (not that we needed to unpack), 2 bathrooms. Full kitchen. Very clean too.
The area was pretty quiet but a short walk to many bars and restaurants as well as a Publix supermarket. I wouldn't hesitate to recommend and I would stay again if I was passing through Miami.
Found the staff good, they did take a €150 security deposit off us on arrival in case we broke/stole/wrecked something which we got back.
