We have done VRBOs both abroad and in the states for many years and have learned that it is about doing research and having the right expectations. The negative review below was posted shortly before we were to arrive at our rental and needless to say, it made us a tad nervous.
Overall, this rental worked perfect for us and it was the beach and water in front of the house and the friendly locals that made it perfect. We swam and snorkeled twice a day everyday and enjoyed greeting and chatting with the locals that showed up every morning and evening to do the same. Besides us, there were no more than 2 or 3 other people on the beach and often we were the only ones. The water is clear and clean with a sandy bottom and we saw great fish and even turtles while snorkeling.
The house is simple with no frills and we ended up enjoying the simpleness of it all. Everything in the house worked and worked well and we were never in need of anything. We cooked about half of our meals at the house and found all the kitchen supplies that we needed. The air conditioners in the bedrooms worked well for cooling and drying the air for sleeping. The beds were comfortable and there were plenty of sheets and towels. The house does need some exterior painting and maintenance, but it did not detract from our experience. After each day of touring around the island, we were always looking forward to coming back to our place to swim and chill.
We would recommend renting a car as it is fun to travel all over the island seeing different sites and areas. It also makes it a bit easier for groceries. During our stay, the beaches down by Bridgetown and the Crane were filled with seaweed and the water had sea lice (stinging larva of jellyfish) which made us appreciate our beach even more!
If you want luxury accommodations or enjoy being with other tourists, this probably isn't the place for you. If you want to experience the real Barbados from a more local perspective, this is a great rental.
