Casa de Madrid is a classy bed and breakfast across the street from the Teatro Real de la Opera, and an intellectual’s dream. Instead of opulent and excessive amenities, over-ingratiating staff and over-the-top interiors, Casa de Madrid makes you feel like a guest in an old, wealthy family’s urban apartments. Parquet floors, classically tasteful furniture, family heirlooms, and replete bookcases will welcome guests in their rooms. Owner Marta Medina, an art historian with a superior eye, has decorated each room with a unique theme, from traditional Spanish with infantas portraits by Velázquez, to courtly 18th-century with toile de Jouy fabrics and Piranesi engravings. The antiquated décor is always sensible and restrained, never kitschy, and is a welcome break from generic luxury hotel chains. Do not expect Zen-like privacy and quiet, nor modern business services, since the Casa has the feeling of bohemian living, sharing someone’s home with others. Book well in advance, since Ms. Medina only offers 7 rooms.
