It is old and small but suffices for short term stay. Staff is helpful with 24 hours front desk and you can leave your luggage after checking out. Just note that they do not have lift so you have to carry your luggage on stairs.
Nice small hotel in the very center of Krakow. Restaurants and Café nearby. Public transport just around the corner. Market place 3 min to walk. Street nois in the morning 6am.
