(477 reviews) The room was the most poorly equipped condo we have ever stayed in. Very few kitchen utensils, tiny skillets, tiny coffee pot. No food storage bags or covered containers. Rusty freezer. The outside facilities were nice, clean pool and hot tub, nice gas grills. Not enough umbrellas for shade. Stayed in E3, below street level. Would not recommend.
