The Tutti Frutti Hostel is one of the best in Krakow! Whenever I go to Krakow I try to stay there, but you have to book in advance, because it is so popular. It is 500 meters from the Church of Santa Maria and the Market Square. The only downside is that there is no elevator and you have to climb stairs. This very clean and rooms of 5, 8 ... with breakfast included!
