The house was very nice and clean, in a small residential "development" one block south of the main "commercial street" of Captiva. It's easy to walk anywhere via the beach or the street.
It's a one minute walk to the pool and maybe two minutes to the beach (via a small wooden path by the pool). The pool is fine. Nothing special, but a good option for the kids at times. The beach is great, though was surprisingly more crowded than expected. Still, we were always able to carve out space for our stuff without having to "get there early to reserve a spot".
Speaking of stuff, we loved the rusty little cart provided and used it a ton to bring all our stuff to the beach (most of which was provided by the host). Chairs, umbrella (we donated a 2nd one to the cause), rafts, pool noodles, etc. There's an outdoor shower (also great) to rinse off all your post-beach sand as well.
Beds were a little lumpy, but fine. Kitchen is nice. Hard to find much of anything to complain about. My favorite part of the house is the screened lanai. Even though the houses are close together, there's so much tropical vegetation, that it feels very private.
I would certainly recommend this house for anyone looking for a nice family stay very close to the beach.
