I'm looking for a beautiful and elegant hotel south of Tulum in Mexico. Nothing rustic. Thanks.?

I saw all the little Hotels they have south of Tulum and they are all sweet,but I'm looking for something a little less rustic and a little more elegant. Not a huge resort with 500 rooms but something small and cly. A good restaurant would be great too. The price isn't too important. Does anyone have an insider tip or an idea? Thanks so much...
