I went backpacking in Curitiba for the first time in July 2012, and I liked it so much that I went back three more times the following year, in February, May, and August. This hostel has a very friendly atmosphere, with different options of dormitories and private rooms, a communal kitchen and garden. It has an excellent location, in one of the most beautiful areas in the whole city. The staff are friendly and attentive, and the owner tends to hold a party every Sunday on the large balcony, with a caipirinha for every guest. I had a great time here, meeting people with fascinating stories to share from all over the world.
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!
Next door to one of the best bars in the city, the Alemo (where guests of the hostel have a great discount!), this is a beautiful building, with wood everywhere. Some old details have been preserved, and the rooms are all very clean, with hot water (important in the cold of Curitiba). This is unique for its Japanese style: small rooms with space for no more than a bed and a small suitcase.
The Slaviero Executive Curitiba is located in the beautiful city of Curitiba. It has seventy luxurious rooms decorated in a modern style and which come fully equipped. One of the highlights of the hotel's facilities is its delicious restaurant specializing in regional cuisine as well as international cuisine. It also has an important structure for social as well as business events.
