We had a wonderful week-long stay, at Sandestin, in Tivoli 5262. The place was clean and the beds were comfortable. The location to the pool is outstanding, and having the Golf cart made getting to the beach, Harbor Town and the rest of the resort a breeze. We only had two issues during our stay, and neither really diminished the experience.
The first item is the upstairs unit. There is little to no insulation in the floors, and you hear EVERYTHING. What is people just going about their normal routine comes through quite loud in the unit. We were not annoyed, but it's just something to consider if you are used to living in your own home or with no one living above you. For us, we just wore earplugs to sleep (which I normally do anyway) since the people staying upstairs had little kids that loved to run around their condo later in the evening.
The Second item is the wireless connectivity on the Master bedroom TV, which is horrible. Due to the extremely close proximity to the router, the WiFi was having issues connecting and impacting all of the other devices/TV's in the condo. Since the WiFi router is located right below the TV, I suggest connecting the TV to the router via ethernet cable and disable the Wireless on the TV.
