Please read this review as a counter to all the other ones.
First, the obvious: The apartment is right on the beach which is amazing.
Second, Kim is a great host.
Now, the not so great. The apartment is very dark, without sufficient light. It's hard to read in, and the window shades don't allow for max outside light to enter. So this rental is best for people who don't want to hang out in their place and instead plan to be outside most of the time except for sleeping. Or, an investment in improved lighting would be great.
Also, the apartment is cramped, so there's not much room to stretch out, even for just two people. The shower is mediocre, with rust on the curtain rod.
What's confusing in the pictures is the outdoor lounging area. It's very narrow, except where the round table is, which is a way's up from the boardwalk. The main point here is the concrete patio is a place to sip coffee or wine on upright plastic chairs, but not to lounge at all like on a chaise. While there are sand toys for kids, there are not any beach chairs to take to the sand and lounge there. Which means that the classic beach vacation where you swim, dry off, read, snack, walk/jog then come home to shower isn't really possible. There is an umbrella and a camping chair, but that's not really beachy. So a big improvement would be investing in a couple of simple beach loungers.
Bottom line: the place is functional, but lacking in the ways described above. While being at the water's edge is a treat, the current state of things doesn't make it a great deal, money-wise. For that there would need to be an upgrade that makes the guests feel sumptuous inside and out, rather than just functional.
