Indeed, the Gran Hotel Manzana Kempinski La Habana is the first "true" luxury hotel to open in Havana or in Cuba as a whole so far.
This particular hotel sounds interesting:
Originally built between 1894 and 1917 as the first European style shopping arcade in Cuba, Gran Hotel Manzana Kempinski La Habana is situated in the heart of the old Havana with a direct view of the Capitol and the Great Theater of Havana and amidst UNESCO World Heritage sites.
