Cozy room in Chamberí - Madrid

I live in a cozy apartment in Madrid downtown, in the Chamberí neighborhood. It's a 15-minute walk from Malasaña, 30 minutes from Ópera, and 40 minutes from the Prado and Thyssen-Bornemisza Museums (and just a quick 10-minute metro ride to Atocha and the Reina Sofía Museum). My home is a 2-bedroom apartment with a nice living room, a terrace, a small kitchen, and a bathroom. I live with a 13-year-old doggy, very calm and sweet, who spends most of his time sleeping. The bedroom available is the single one, with a 90 cm bed, a window opening to the terrace, a big wardrobe, a table, a chair, and a ceiling fan. I love to have a quiet ambiance at home, listening to some music while I cook, or watching a movie at night. I speak Spanish, English, and French.
