We had a great stay at Kadetus for 4 days/nights. We had a private room with our own bathroom. There was a common kitchen just outside our room, with a fridge and various utensils, very convenient. Free WiFi in the room worked well. There is a pub in the same building adjacent to the hostel, where they offer free breakfast. The breakfast is simple but very good: corn flakes, milk; slices of bread, ham, cheese, tomatoes, cucumbers; cream cheese, jam, tea, coffee. We also got free coupons for some coffee/tea options in the same pub for the afternoon. The location is quiet but very central, 10 min walk to the Main Market Square, 10-15 min walk to the Wawel Castle hill. There is a mini-market open 24 hours just 100 meters away, and a bigger supermarket another 100 m or so in the same direction. The hostel offers drop-off laundry services. The hostel staff are very helpful. Overall: no complaints whatsoever, would gladly stay there again.
