Review for Palms Casino - Madrid Review For Palms Casino - Madrid Google User Jul 13 '16 at 8:19 This is a massive hotel (almost 4 in 1) separated into four different blocks.

Had I not known this was a 4-star hotel I may have considered it 5 stars based on its array of offerings, quality of it's breakfast buffet, and other factors. View full site to comment or like
