A big house
The Knock Knock Hostel is run by three Argentinians who have been living in the city of Curitiba for a few years. It's a big house, composed of several shared rooms, some of which have a private bathroom. The breakfast is included in the better rooms. The decor is all musical, with vinyl on the wall, and rooms named after dance rhythms like tango and flamenco. It has a barbecue and an open area with hammocks. The hostel provides blankets, bedding, and towels, and offers tango classes. It also has a television room and ping pong!
