My family and I recently rented this house for a week and I highly recommend it.
The reason we chose this house was the location and we were not disappointed. This house has water on two sides and gives an unparalleled view of Siesta Beach as well as the gulf depending on which of the many decks you are on or which direction you looked. Many people on the beach asked us if it was our house and commented on how cool it looked and how it had an amazing location. My parents said it made them feel like the 'rich and famous!'
The house itself is very spacious with more than enough room for the six of us who stayed there. The rooms are all big enough for family time together, but also spread out enough for private time as well. The house is definitely a 70's style house but is very well maintained and has nice, comfortable leather furniture in many rooms. Some of the external screen doors to the decks were a bit worn and hard to maneuver, but for a doors exposed to gulf weather 365 days a year it was understandable.
The only mildly negative thing I can think of is the beach beneath the private beach access stairs appear to have eroded away leaving about a two and half foot step down after the last step. My mother has a bum hip and had a bit of trouble getting up and down the stairs. I spent some time and engineered some new steps out of rocks and concrete slabs that were nearby and that made it much easier for her, but I suspect the surf and weather will wash my make ship steps away before too long. Beaches and sand raise and lower all the time so we weren't too too bothered by this, but I suspect those stairs may need more permanent work at some point.
As a whole we were very happy with the house and we are already making plans to come back next year.
