My wife and 3 children recently rented this condo last minute. We contacted the owner directly via email and she was very responsive. Ultimately, she referred us to a professional agency that manages the rental -- great for peace of mind should anything go wrong. Rental agency was easy to deal with as well.
The unit was bright and had fairly updated furnishings, including a nice, big flat screen in the main room. Beds were comfortable. There was an air/spring mattress in a sofa bed. Whoever stayed prior to us used the mattress only in the second bedroom (it was found in the closet already blown up), so we did the same. Has dishes, coffee maker, toaster, wine glasses, etc. all you'd need. Appliances are dated, but we did not cook much beyond a frozen pizza...oven worked fine.
There is no in-unit washer/dryer, though there is a public one on the floor. Owner provided some beach chairs and umbrellas, which is nice. There is shaded, covered parking, you don't have access to the storage closet by the parking spot, however (i.e., you need to bring beach toys, chairs, etc. up each night, or do like we did and just leave them in your car). Elevator is at the far end away from the beach, so we ended up just using the stairs a lot...no issue, but unloading / loading could require a few trips.
You have a slight (angled) view of the ocean from the unit, which is nice. Pool was nice and convenient and never crowded. The main resort (the one owned by LXR, I believe) is just down the beach. It looks a little tired, and we did not feel like we were missing out by not staying or paying to access the resort proper. Note: you can walk down and grab lunch or drinks at the beachside bar. Food was pretty good, and it makes for an easy lunch without leaving the beach. Good happy hour as well! Sanibel is great, location of this unit is convenient to restaurants, grocery store, pharmacy, and activities.
Overall, we enjoyed our stay.
High notes: Clean unit, quiet complex, nice TV, comfortable furnishings.
Low notes: Sundial complex WiFi is *very* slow so if you need video conferencing or the like, you'll be out of luck. I'd hesitate to do a working vacation here for this reason.
Recommendations to owner: maybe add a wireless router in unit, washer/dryer, rug for main room to warm it up a bit.
