Clean newly renovated. Staff was so friendly. We had a great time. Highly recommend

It was such a lovely place. Great pools, fun tiki bar during the day and great rooftop happy hour in the evening. The restaurant on site is delicious. There’s a market on site that had so many great wines, snacks, deli & breakfast too.
