Gran Melia Palacio de Los Duques is undoubtedly one of the most iconic 5-star luxury hotels not only in Madrid but probably worldwide.
The building itself is a combination of two renovated historic buildings - a 13th-century convent and a 19th-century palace. It's located in the picturesque area right next to The Royal Palace, The Opera House, and The Cathedral.
Some of the facilities include a Thai room wellness centre, fitness centre, cocktail bar and a breathtaking rooftop swimming pool with 360º view of the city.
