We stayed in Janthina 1A and it worked great for our first stay in Sanibel. It was clean, spacious, and comfortable. The views and location were great – overlooks the Gulf, steps from the beach, (which felt quiet and private) and had a small, but clean pool we could take a dip in after retreating from the beach. It's also an easy drive to Bailey's Grocery and Hardware – which we frequented daily for our morning coffee, beach toys and blow ups, groceries (you name it, they have it); Joey's Custard and Doc Fords.
We went for this unit because of it's value and felt like we got what we paid for. Yes, the bathrooms and kitchen need to be updated and there's a few little details that could be fine-tuned – like replacing broken screens in the bedrooms, fixing a missing tile in the hallway, replacing rusty beach equipment (which we didn't use but instead rented inexpensively from YOLO in Captiva), and getting a new mattress for one of the twin beds which was so stiff that no one could sleep on it – but overall we had a lot of room for our group of 5, it was very clean and comfortable, and the main living space and bedrooms were very nice and in good taste.
Management was also very responsive to our questions and requests. My only other comment is that they could keep a few more amenities on hand and provide some more direction on where things are located. For example, after a day or two in we found a better beach chair in the closet, and the beach towels. It was stocked with a lot of wine glasses and tableware, but no salt and pepper, only one garbage bag, one roll of toilet paper in each bathroom, and the bags we were supposed to put our dirty linens in at the end of the week were not found. None of these were deal breakers, but would be nice to haves. The check in and check out process was very easy.
We'd definitely consider staying here again!
