We enjoyed our stay at Jeff's place. The location was great with the beach just a short walk out the backdoor. You get two beach chairs for the unit. We had 3 people but it worked out. On non-busy days, we were able to snag another chair. On busy days, we just sat in the sand. The boardwalk is about a $12 Uber ride away or a 45 min walk. To get to downtown Miami is a bit of a hike because of (constant) traffic on the expressway, just so you know. We did have to wait in line a bit to check in since the condo is run inside a hotel and there happened to be multiple groups ahead of us. At other times there was no wait so that just depends. Make sure to put all your guests on the reservation to avoid trouble at check-in.
I will say that the kitchen is very sparse...only 2 coffee mugs, and no hand towels or dishrags to wash dishes. There is a dishwasher and pods as well as paper towels. No spices or cooking oils or anything left from past guests at all so plan accordingly.
