I spent several nights at Tournet hotel in Krakow for which I paid approximately €20 (80 PLN) per night. That was much cheaper than the place I stayed at last time I visited Krakow when I stayed in the Old Town.
Tournet is in the old Jewish district, Kazimierz. This is a more authentic part of Krakow as most of the people in the shops and bars in the area were locals, not tourists. It is about a 10 to 15 minute walk to the Old Town's historical attractions. Late at night some of the nearby streets could feel a bit deserted but at no time did it feel unsafe.
The hotel itself is on a narrow street just off a main road so it is easy to find. (A 20 minute walk from the main train station). On arrival I was given several keys; one for the front door, as there is no reception after about a certain time - 10pm, I think; one for the door leading to the hallway across the courtyard where the room was located; and one for the room itself.
Though the room was small, as expected at this price, good use was made of the space available with shelves, a small table to eat at, a closet, and a bathroom with toilet, sink and shower. (The shower worked as well!).
Each morning breakfast was given to me at reception in a brown paper bag. It consisted of two bread buns, three or four slices of ham, jams, and a fruit drink box. Coffee/tea kettle etc, and kitchen utencils all in the room.
The room was also fairly well heated and clean. All staff spoke fluent English.
For the price it was well worth it. I'll stay there again should I return to Krakow.
