Time Out says
Founded in 1880, this small theatre is one of the oldest and most beautiful in Madrid (whose classical atmosphere takes you back to the days of going to an authentic theatre). It's managed to survive various crises (and was even closed for a number of years), and its billboard now includes innovative works, occasional concerts and children’s shows... always with a retro atmosphere that has its downside in that it lacks comforts you'd expect from a modern theatre.
