Let's start with the house. It's exactly as described, no surprises. It's perfect and has everything you need, we had 8 people comfortably. Even the sofa sleeper was very comfortable. Very spacious, well-equipped kitchen (agree with other comments that some non-stick cookware would be helpful), gas grill was easy to use, backyard was very nice and well lit, 4 bikes and beach furniture were great. The location was great. In a small, quiet community, no noise, no traffic. We loved the house and would definitely stay there again. The small plaza right next door was super nice and had a few good restaurants and some shopping, beautiful square with outdoor entertainment nightly. Within walking distance. The "Destin Ice Market" was just beyond the plaza, and should not be missed. The name is deceiving, this upscale little grocery has everything you could possibly want, including liquor store, wine, beer, fresh seafood, meats, cheeses, baked goods, etc. Beautiful place and very well stocked. Wish I would have found it sooner in our trip. We did not use the pool, but it looked nice and was never busy.
As others have mentioned, you do need to cross rt. 98, which is a very busy road, to get to the beach and to the "30A strip", Rosemary Beach, etc. Was not an issue for us, but could be for those with children. I'd recommend riding the bikes to the beach because parking is not available at some access points and limited at others. Easy bike ride but it would be a bit of a long walk, but manageable if not carrying a lot and don't mind the walk.
Now for Rosemary Beach. We were there spring break week, so maybe this is not typical, but the place was absolutely overrun with teenagers. Throngs of 20-30 teens roaming the sidewalks while blaring music and racing their bikes & cars everywhere. I'm surprised there aren't more accidents. Young kids, junior high or high school aged. I've never seen anything quite like it. Most were rude and made walking or riding bikes there very difficult. We rented some additional bikes and had one stolen on our very first night (it was later found in the weeds at a Rosemary Beach hotel by their maintenance staff). This is apparently a well known problem there, as there are signs all over indicating an 8:00PM curfew for those under 18, but it was simply unenforceable as the cops were outnumbered 100 to 1. Lock up your bikes! I would avoid Rosemary at spring break unless you need a trip back to jr. high.
