The Cactus Casita contends for the best place I've ever stayed using Airbnb! The guest house was decorated beautifully, incredibly clean, and had high quality, modern amenities. The location is perfect - walking distance to shops and restaurants in South Park, ample parking, safe neighborhood, etc. Even when there was a plumbing issue in the kitchen, Leslie was quick to respond and it was resolved within a day and without inconvenience.
Really can't say enough good things about it - you can't get better quality for the price, so if you're thinking of booking here you should definitely do it!
